>> From the Library of Congress in Washington D.C. [ Silence ] >> Daniel Boomhower: Good evening I'm Daniel Boomhower I'm the head of reader services here in the music division of the Library of Congress and I want to warn you in advance that the talk I'm going to give is, if you wondered what it would be like to hear an academic paper given by a musicologist this is your chance, but I also know that our concert audience is a very sophisticated audience and will have no problem keeping up with the arcane details that I will kind of subject you to and also one of the things that I think is really a great opportunity, you know, having a concert series in this fantastic concert hall and the series we present here at the Library of Congress in a library is a fairly unique thing, and what most of our concert audience may miss in this process is the fact that there's one of the greatest library's in the world surrounding during this process and concerts are how we in the music division make our collections come to life, but research in our collections is really this sort backbone of what we do and this is an opportunity I hope to kind of show you what the collections here enable in terms of the kind of information that we can glean about music history and music culture in previous centuries as you will soon see. So, tonight's concert features Mahan Esfahani with music of the Bach family, Johann Sebastian Bach and Wilhelm Friedemann Bach, as well as Carl Phillipp Emanuel Bach. There are also two pieces of 20th century composers on the program tonight. The concert tonight is part of two event series so to speak focusing on the music of Carl Phillipp Emanuel Bach who was born 300 years ago in Weimar, Germany. To the extent that he is known today, C.P.E. Bach is primarily remembered as one of several sons of Johann Sebastian Bach, possibly also remembered as the author as of a treatise on the keyboard and there is the chance that an average concert goer has heard some of C.P.E. Bach's music. Yet, in his own day, the fame of Carl Phillipp Emanuel Back far exceeded that of his father, and in fact, the music collection here at the Library of Congress reflects the interest in C.P.E. Bach's music that remains strong throughout the 19th and early 20th century. The story of the C.P.E. Bach sources at the Library of Congress consists of several different threads each spun out of the interests and motivations of musicians and collectors over nearly 300 years. As a whole, this collection of C.P.E. Bach materials documents the acquisition practices and strategies of a fledgling American research library at the beginning of the 20th century. At the same time, separate groupings of materials helped to fill out a picture of 18th century performance history in Northern Europe, and documents the music collecting of individuals in the 19th century. Besides the 85 examples at the Library of Congress of Bach's music printed during his lifetime, the collection includes 1 autograph manuscript of a single keyboard fantasia, and that's on display in the foyer of the Coolidge Auditorium. There are also 3 autographed letters, and in my opinion, most interestingly our holdings include 74 copious manuscripts and 5 more that are misattributed to Bach and these offer evidence of how individuals within and beyond C.P.E. Bach's immediate circle of colleagues engaged with the composer's music. So, tonight I will attempt to do two things in this brief introduction to a noteworthy portion of the library's music collections. First I'll explain how this rich collection of C.P.E. Bach materials came to be held at the Library of Congress then I will describe how these materials reflect 18th and 19th century musical life, particularly in Berlin. In doing this, I will risk like I said, presenting an abundance of scholarly detail, because in part I know our concert audience will appreciate such information, but also because I want to offer evidence of the kind of research that the collection here at the library support. Tomorrow evening I will be joined by two of the editors of the complete works of C.P.E. Bach to discuss the composer's music in further detail and to explore the process by which a scholarly addition of music is prepared. On about August 1ts, 1902, Oscar Sonneck began his duties as the second chief of the music division at the Library of Congress. He would conduct his initial work while in Europe armed with letters of introduction to European libraries and book dealers from the ambitious Librarian of Congress Herbert Putnam. Putnam had served as the Librarian of Congress since April of 1899 and had embarked on a mission proposed in 1896 by him and 9 other witnesses before the joint congressional committee on Library of Congress. In those recommendations, they proposed to create something more than a repository of copier of records or legislative library, but a true national library. Sonneck embraced Putnam's [inaudible], I'll show you, here's a picture of Oscar Sonneck he's the short fellow in the very center of the front row. He was fairly young, I think he was under 40 when he was appointed Librarian of Congress and then he is surrounded by the division chiefs of the library at that time. Oscar Sonneck is pictured in this in the second row and I'm going point to him directly cause it's hard to explain, cause the rows aren't quite as clear as you hope. This is Oscar Sonneck, right there, second. I say that second from the right, in the second row, but it's hard to tell. Anyways, Sonneck was I believe hardly 30 when he was appointed the chief of the music division. So Sonneck embraced Putnam's charge and sought to "provide a reasonably comprehensive collection of all material bearing in any way on music in America and more particularly on American music." In this Sonneck held the view as described by him in 1908 that "American music as the product of America brings and American industry is deemed to be a paramount importance in our national library, yet the peculiar development and status of music in America being mainly a reflex of music in Europe compelled the Library of Congress to collect the musical product of European brains and industry in the same manner as European libraries do, or would like to do." Sonneck further stated "Beginning with the 18th century" and his article adds emphasis, "The library of Congress aims at a collection of music and books on music sufficiently comprehensive to ultimately relieve the American scholar of the necessity of consulting European libraries, except for research not bearing directly or indirectly on music in America as a reflex of music in Europe." Later in the same essay, Sonneck observes a result of this strategy. "The Library of Congress collection is growing rapidly into something really useful to the historian and we already possess quite a few things, particularly in manuscript or of English imprint that are not frequently found. We appear to have, for instance, some symphonies by that master of strange epicurean tastes Anton Filtz not mentioned in Hugo Riemann's bibliography. We have about 30 of the 45 [inaudible] of C.P.E. Bach and we were able to supply some of Haydn's unpublished divertimenti to the editors of the complete edition of his works now in process of publication. In building the collection at the Library of Congress, Sonneck sought to make available a comprehensive reference collection of the literature about music and the existing musical repertory. In this he would in general only acquire single copy of a composition even if additional variant manuscript sources might become available and he seems to have been willing to delay the purchase of printed additions in order to take advantage of the availability of manuscripts of unpublished works that presumably would be far more scarce. In any event, we have in the music division collections an annotative copy of the 1905 sematic catalog of C.P.E. Bach's works which demonstrates the comprehensiveness of the efforts of successive generations of staff at the Library of Congress to collect this composer's music, and it's obvious because it's annotated with the things we have and the things that we don't have. Interestingly, the existing collection of C.P.E. Bach materials has attained a relevance that Sonneck might not ever have imagined. With the publishing of the complete works of C.P.E. Bach well underway, which we will discuss here tomorrow evening, access to this music will no longer present the challenge it did in the early 20th century and scholarship can now more successfully consider the music in the broader context of 18th century life, and in fact a growing body of scholarships seeks to contextualize Bach's compositions, not only musically, but also within society. In this research the non-autographed manuscript sources offer a lens onto the musical interests and practices of previous centuries and the manuscript musical sources at the Library of Congress offer an entree into musical and social settings that often lack documentation in other contemporary accounts. In the early years of the 20th century, one specific Berlin antiquarian book dealer played an essential role in making it possible for the Library of Congress to acquire the collection we now possess of C.P.E. Bach's music. The firm Leo Leipmannsshohn operated under its founder's name from 1874 until 1936; however, in 1903 at about the time that the Library of Congress began buying from the firm, Leipmannssohn sold the company to a young colleague by the name of Otto Haas. From Haas and the Leipmannssohn firm the Library of Congress acquired 18th century C.P.E. Bach materials stemming from a handful of important 19th century collections. Tonight I want to focus on one of these 19th century collections, that of Eduard Grell a brilliant composer, conductor, organist, teacher, and director of the Berlin Sing-Akademie from 1853 to 1876. This collection, as I will discuss, has deep roots in Berlin musical life in the 18th century. The items from Grell's collections generally bear a cipher, this is an item from the collection. They bear a cipher in pencil containing the letters GR, and you can see that towards the top of the manuscript, it's fairly faint in pencil and this GR is usually followed by a 3 or 4 digit number. The GR numbering was seemingly added in preparation for the sale of the music collection, Grell's music collection, by Liepmannssohn following Grell's death in 1886. The significance of the GR numbers remains entirely allusive though; the numbers do not refer to the numbering in Liepmannssohn's sales catalogs and appear on items that originated, not just in Grell's collection, but also on items from the collections of another Berlin, two other Berlin musicians Franz Krommer and also possibly Bill [inaudible] whose music collections were sold by Leipmannssohn alongside of Grell's collection. In fact, in some instances the presence of a GR number on items with Franz Krommer's owners mark have led individuals to presume that Grell acquired those items from Krommer; that Grell died in 1886 and Krommer died in 1887 would at least preclude the possibility that Grell acquired items from the estate of Krommer though. Rather the frequent addition in pencil, and I have, so the frequent addition in pencil of the time signature and key signatures on title pages as seen very, very faintly in this example , this is a sonata manuscript of trio sonata by Johann Gottlieb Graun and. [ Inaudible ] So, you can see on the right hand middle third of page H and then a lower case m and then 4/4 that refers to h-Moll and the time signature of 4/4 h-Moll would be German for B minor, it would take a long time to explain how h got to be used for B but. So this numbering, or this additional information the key signature and time signature conforms with the descriptive practices found in Liepmannssohn's catalogs and it, because of this it's seems most likely that someone working at Liepmannssohn on the sale of these collections applied the GR numbers indiscriminately to Grell's materials, as well as Krommer and possibly [inaudible]. While occasionally objects from Grell's collection also bear a stamp with Grell's name, the modern Bach scholar, the current director of the Bach-Archiv Leipzig, Peter Wollny has observed that a different marking might allow one to distinguish items from Grell's collection. Most manuscripts presume to be from Grell's collection have a consistent numbering pattern where the abbreviation NO appears in the lower center to right hand side of the title pages followed by a two or three digit number and a period; the distinctive cursive script of the capital N easily distinguishes this numbering scheme, does everybody see that at the bottom of the page there? Based on the evidence at the Library of Congress, I believe that Wollny has correctly identified this numbering scheme as, in fact, Grell's own personal numbering scheme. Born in Berlin in 1800 into a musical family, Eduard Grell studied composition with Carl Friedrich Zelter and Carl Friedrich Rungenhagen who were successive directors of the Sing-Akademie in Berlin. In 1829, he began teaching at what would become the Royale Institute of Church Music and held the position of organist at the Berlin Cathedral from 1839, prior to which he had served from the age of 18 as organist at St. Nikolaikirche in Berlin. In 1853, Grell succeeded his teacher Rungenhagen as director of the famous Berlin Sing-Akademie. Until recently, Grell's work had not garnered significant intention since shortly after his death. His student Heinrich Bellermann produced two substantial publications in the late 1880's, a biography and a collection of Grell's essays. These two publications placed great emphasis on Grell's promotion of A cappella vocal music, and in particular on compositions in the style of Palestrina. The abundance of instrumental music from Grell's collection now held Library of Congress would however seem to challenge the image of Grell promoted among his followers that of a, one specifically and solely devoted to this idea of A cappella, Palestrina Lake vocal music and that, so Bellermann's sort of image of Grell was what gained traction; however I think this large amount of 18th century manuscript material of instrumental music sort of contradicts that notion. While the significance of Grell's Bach collection has received passing mention by scholars with particular reference to the need for more study of it, the enormity and broad scope of his entire music collection remains unconsidered. This C.P.E. Bach manuscripts here at the Library of Congress that can be confidently linked to Grell's collection consists of three groups of materials, there are six concertos of which three are misattributed to C.P.E. Bach, two chorales compositions and 11 trio sonatas. Following Grell's death, a French collector by the name of Lasserre appears to have purchased the concertos and trio sonatas from Grell's collection through Liepmannssohn in about 1889. They came to Library of Congress in 1907, again through the agency of Liepmannssohn. Two manuscripts of C.P.E. Bach's vocal compositions that come from Grell's collection came to the Library of Congress in a large purchase again from Liepmannssohn this time in the year of 1908. This was a large collection of vocal music that belonged to Julius Stockhausen the singer and close colleague of Johannes Brahms. Stockhausen presumably also acquired these manuscripts, the C.P.E. Bach manuscripts, from the 1889 sale, Liepmannssohn's sell of Grell's collection. In no instance, in the Library of Congress manuscripts is Grell's numbering, the NO pattern at the bottom of the page, in no instance is Grell's numbering struck through; however Grell's numbering scheme appears to replace an earlier scheme found in the upper right hand corner sometimes more than one numbering scheme as you can see in this instance, and that's particularly evident in the trio sonatas of C.P.E. Bach's music. The canceled numbering scheme is also present in the at least 32 other manuscripts of trio sonatas of 18th century Berlin origin that are held here at the Library of Congress. This is one more example, it's a trio sonata by Johann Philipp Kirnberger, you can see in the upper right that 217 is crossed out. As seen elsewhere in this group of manuscripts, this being one good example, the C.P.E. Bach items bear clear indication that the individual that numbered the items or had the items numbered in the upper right hand corner had acquired or commissioned items in groups. This is exhibited because there are successive groupings of items in the hand of different copyists, so 5 manuscripts in the hand of 1 copyist another 5 or 6 in the hand of another copyist, so it would seem that whoever owned these before Grell, excuse me, acquired a chunk of manuscripts and then acquired another and another and they are number sequentially so you can see 1 group of manuscripts and then the numbering flows right into the next group which is completely distinct different copyists and it's on different paper, so. One fairly consistent characteristic among all of these tri sonatas manuscripts that indicates the relationship between these sonatas in addition to the consistent numbering scheme in the upper right hand corner, is the recurring presence of materials in the hand of, or that in some can be linked with an individual by the name of Johann Friedrich Hering [assumed spelling]. Hering as you can see signed his name at the bottom right hand corner of this manuscript. Hering was maintained close contact with C.P.E. Bach, in addition to this he served as an agent in the sale of C.P.E. Bach's publications after Bach had moved from Berlin in 1768 to Hamburg. Hering also appears to have served as a private music teacher in Berlin. He himself would collect and copy for his collection sophisticated repertoire, but the Peabody Conservatory professor Andrew Tully has documented that Hering prepared manuscripts of simpler repertoire presumably for his students, otherwise, little else is known about Herring or the extent of the collection of music he amassed for rather than on commission. A numbering sequence found on the lower left hand side of the C.P.E. Bach manuscripts of the trio sonatas here at the library appears to be in Hering's hand and offers one indication that these items comprise a portion of Hering's personal collection, so it's number 10 in the bottom right in parentheses, I'm sorry bottom left in parentheses under the musical [inaudible] of it. If the numbering scheme on the lower left is Hering's the numbering in the upper right would presumably represent an intermediate owner between Hering and Grell. In the instance of the C.P.E. Bach manuscripts at the Library of Congress, the practice of preparing manuscripts for students may converge with Hering's own personal practice of copying highly sophisticated music of the Bach family for his own collection. Hering's students included an individual by the name of Otto Von Haas a member of a well-establish noble oppression family and eventually a prominent official in the oppression government during the late 18th and early 19th century for about a year or two during the Napoleonic wars the Prime Minister of Prussia under Friedrich Wilhelm III, but he didn't necessarily agree with his King very well, so it was a short lived relationship. Otto Von Haas built, in his free time, built a noteworthy music collection that in part supported an active musical [inaudible] in Berlin during the first decade of the 19th century. His son Otto Von Haas, Jr. continued to refine, expand and catalog the collection. In a study of the Von Haas collection, the German scholar Bonita Faulstich [assumed spelling] elaborates on the relationship of Herring with his noble family noting that a member of the Haas family served as a witness to Hering last will and testament dated September 1810, and in addition to this, a significant body of material and the Haas collection came from Hering's estate. Eduard Grell's possession of Hering's manuscripts may reflect that the Haas family manuscripts later came into the collection of the Sing-Akademie though there's no concrete evidence of this, there are a lot of similarities between the Haas collection and material that is found in the Sing-Akademie collection that was only recently rediscovered in Kiev of all places. So along these same lines, I'd like to discuss another collection of manuscripts that may also have comprised a portion of Grell's collection, and prior to that possibly Haas's collection. This is an example actually before I move on, this is an example of Hering's musical hand that's a fairly, actually you stare at these pages for long enough and they either become extremely distinct or look all the same, but this is a fairly good example of Hering's hand and I don't think anyone would be confused about it. We have other manuscripts the 50 something trio sonatas that all came from Grell's collection. I, again, you stare at these long enough and you can't tell heads or tails of anything, but it really appears that even in items that aren't in Hering's hand they have his [inaudible] figurations these numbers above the baseline here which are for the chords to be played above the music. It really looks like Hering's hand that, you know, if we got 20 people to a rate 6's and 5's and 7's and flat signs and sharps signs and natural signs, I'm sure we would all start to confuse all 20 of our numbers as well, so I'm inclined to think that most of these manuscripts were emanated from either Hering, Hering's collection, or were works that Hering was selling; like he sold printed music in anyway. This is an example of another group of materials that I want to talk about. In these instant, in this material there are none of the tell-tell indicators of Grell's ownership, that NO and a number, not here; not of what I think is presumably a sign of the Haas family's ownership, so those numbers in the upper right hand corner, there are no small numbers in the upper right hand corner. At the same time, these manuscripts do display yet a different consistent numbering scheme strikingly rendered in dark black ink with a thickly drawn N followed by successive numbers and you can see that right after the title Concerto in G. The numbering appears to restart with different composers and different genre by the same composer. Among the C.P.E. Bach concerto manuscripts baring this distinctive numbering sequence two different groups appear. The first group reflects the work of several professional Berlin copyists closely associated with C.P.E. Bach and even though they're closely associated with C.P.E. Bach, we absolutely have no idea of their identity and they continue to be referred to in Bach's scholarship as anonymous 302 and anonymous 303; those are largely arbitrarily assigned numbers, again I could go on for a while about how they got to be 302 and 303, but for intents and purposes they're arbitrary. Another Berlin copyist identified as F. Baumann [assumed spelling] also appears consistently among this first group of manuscripts and this in fact, this title page is in the hand of F. Baumann, again all we know of this guy is that his name his first initial was F and his last name Baumann. There is a second group of concerto manuscripts music of C.P.E. Bach that also fall into this numbering sequence. The second group reflects at least in part the work of amateur copyists working under the supervision of a copyist referenced by the scholar Rachel Wade this copyist K, again entirely arbitrarily assigned moniker for this copyist. The grouping become discernable not only by the presence of specific copyists, so we've got our professional copyists on one hand and then those amateur copyists on the other, but they also have consistent paper that used in the two groupings. Additional manuscripts of the Bibliotheque Nationale de France from Lesserre's collection also bear the same numbering pattern, as well as at least one in the collection of the Berlin Sing-Akademie. In the earlier of the two groups, the group of concerto manuscripts that were not prepared by the professional copyists, specifically anonymous 302, their, so anonymous 302 is soft of consistently present in these and he is an individual who worked for Bach between 1745 and 1759, but anonymous 302 produced many of these manuscripts offer strong evidence for the dating of the [inaudible] so they couldn't have been prepared before 1745 or after 1759. In addition, he and his fellow copyist used the paper for these manuscripts shown today from the 1740's and perhaps from the early 1750's. Finally, the scholar and keyboard player David Schoolenberg [assumed spelling] has observed that the versions of the concertos contained in the manuscripts produced by anonymous 302 document intermediate versions of the compositions that date to about 1755, and it was at this time Bach was continuing to revise these concertos; so the versions of the concertos that are here in the Library of Congress collection are not the final form that the concertos would take. Regardless of the inconsistencies between these two groups of manuscripts, not only their sequential numbering, but also their subsequent transmission clearly reflect their integrity as a covius of collection. Leo Liepmannssohn's catalog number 75, which was published in 1889, listed these manuscripts as components of lot number 96 and now it appeared on page 4 of this catalog. The items correspond not only in description to the items held at the Library of Congress, these manuscripts also bear the exact numbering in Liepmannssohn's catalog. Small notes in the upper left hand corner of several of the Bach manuscripts reflect the numbering of the separate manuscripts listed in Liepmannssohn's catalog, so though Leipmannsohn's numbering of the manuscripts does not maintain the earlier numbering pattern, so in this instance number 8 is now number 4 you can see faintly in the upper left hand corner that's just a 4 and a period. The grouping of these manuscripts together by Liepmannssohn and his sales catalog indicate and obvious cohesiveness. The lack of individual pricing for the manuscripts listed for sale as a group, and they were prices at 16 marks for I think it was about 12 manuscripts, in 1889 that suggests that Liepmannssohn sold these as 1 single lot at that time. This I know you can't, well I don't want to you know. [ Silence ] You definitely cannot see this in this photo, but there on the library's manuscripts these in particular there's a very faint oval shaped stamp that's in purple ink and that's how we know that this collector, this French collector by the name of Lesserre later owned these manuscripts and other materials from Lessarre's collection are held at Harvard and I think there are some at Berkeley, there definitely some at the Bibliotheque Nationale, all of those the stamp, oh and the University of Michigan, the stamp is very clearly present so it seems that the Library of Congress scratched off the stamp after they acquired the items; why I don't know. However, Lesserre's collection was sold in 1907 and it was at that time that this group of 12 or so manuscripts that were sold as 1 lot in 1889 were dispersed and so the faint traces of the collector's stamp on our manuscripts suggest that Lesserre acquired these at the 1889 sale, but that subsequently several manuscripts that matched those at the Library of Congress but were turned down by Oscar Sonneck became incorporated into the holdings of the Bibiotheque Nationale. Despite the abundant information about their 19th century owners, the individuals who originally placed the distinctive numbering on these Bach concertos and, as well as a group of C.P.E. Bach sonatas, left no trace of his or her identity. However, another group of concertos at the Library of Congress may offer evidence of the origins of these materials. This group again displaying the distinctive numbering pattern, this is an example of it, so here we have N4 in the top right hand corner, they displayed a consistent numbering pattern; they contained key word concertos by an individual named Christian Friedrich Shaula [assumed spelling] he was a Berlin contemporary of C.P.E. Bach's and a colleague of Bach's and Fredrick the Great court orchestra. No copyist or watermarks, well I don't think the copyists are water, I know the watermarks are not consistent between these Shaula manuscripts and the Bach manuscripts, I'm not sure about the copyists cause I can't tell if this Baumann or not. In any event, there doesn't seem to be the strong correlation between the Shaula manuscript and the Bach manuscripts. The only consistent trace of relationship between these manuscripts is the numbering scheme; despite the lack of any discernable physical evidence left by the earliest owner's, the presence of Shaula's music among these items offers a revealing glimpse into the vibrant musical cult life cultivated in private societies in which Shaula maintained a prominent role. He was both a member of a group known as the Musik uben Gesellschaft which translates to Music Practicing Society and also is the director, this is in the 1750's, 60's, and 70's he was the director of the Musikalische Montage or The Musical Assembly comprised of his colleagues in both instances most of the members of these societies were also members of the Fredrick the Great's court orchestra. Bach was not a member of any of these societies, but maintained close contact with the musicians involved in them and his music enjoyed frequent performance in these settings. The presence among these manuscripts of 2 Bach's primary copyists from this period legitimates their authority and suggests that they were prepared at Bach's best were on commission for use in Berlin where they remained until late in the 19th century. So important information has begun to emerge about these and related materials through composer center research and especially in the work of the editors of the complete works of Carl Philipp Emaneul Bach. What is of particular interest to me is what these sources reveal when placed within the context of their origin and dissemination, as they offer insight not only into the professional connections C.P.E. Bach maintained in Berlin, but also give evidence how these musicians use the composer's music as a public music culture developed in the waning years of the 18th century. Given both its extraordinary breath and depth, the collection that Oscar Sonneck built here at the Library of Congress has as he had hoped created the opportunity for substantive historical research in the United States. However, given the important connections this collection holds with sources held at many other institutions, rather than freeing American scholars from reliance on European libraries, scholarship utilizing our collection continues to strengthen the bonds of the Library of Congress to its counterparts in Europe. Given that our weekend concerts are cosponsored by the Geothe-Institut and the German Foreign Office, I can't think of a better way to conclude my remarks than in making this observation. So I thank you for joining us here at the Library of Congress for this evening's concert and I would be happy to respond to observations you may have. [ Applause ] And now that you've had a taste of a musicological paper, I can only wait to see you all at the meetings of the American Musicological Society. >> Yeah, I have a question for you. >> Daniel Boomhower: Yes. >> Does the library possess the, any manuscripts from the most famous of the Bach copyists anonymous 4? >> Daniel Boomhower: Just so you all heard of anonymous 4, well anonymous 4 was a composer working in 13th century Paris, so anonymous 4 was definitely not associated with C.P.E. Bach. Oh, and there's a great vocal, female vocal ensemble in the United States by the name of anonymous 4. [ Inaudible Question ] One musical manuscript and 3 letters. >> And what was the name of the letters? >> Daniel Boomhower: It's Fantasia and I'm sorry to say I don't know in what key I can give you the sematic thematic catalog number which is 61/3 but that was, it's interesting because C.P.E. Bach's kind of signature musical style was sort of improvisational music and the Fantasia is sort of the hallmark of that so it's particularly nice example. It's on display here in the lobby and actually not even late in life, but halfway through, C.P.E. Bach's life, his handwriting became very shaky and it's very evident in this manuscript, it's like he was writing on a bouncing buggy of something when he was copying. [ Inaudible Question] >> Daniel Boomhower: This would be a late, I would say it's from, if someone knows, I don't personally, but I would say it, 1784 or after. There you go. Yeah. >> Oh, thank you. This might be a little left field, but could you talk about the relationship between Leip-Zig and Berlin and you said Kiev was a little bit, well so out of there, but there were publishers that published in the late 19th century out of both Leip-Zig and Kiev and [inaudible] publishers. Daniel Boomhower: Right. >> Do you know about this and can you speak to this? >> Daniel Boomhower: Well, I yes. So, they Kiev piece of this puzzle is purely the result of 20th century geopolitics. The Russian army occupied the northeast quadrant of Berlin in which the Berlin, well at that time the Prussian State Library existed and still exists on Unter de Linden and it's immediately adjacent to the Berlin University and the next building over on Unter de Linden going east is the Sing-Akademie building. The Sing-Akademie collection was housed in the Prussian State Library, but then all of the holdings of the Prussian State Library during the bombing raids were moved to mines, various mines in Germany; some of them were in the western zone and came into allies hands and those were generally returned to Germany. The one's in the eastern zones were generally retained by the occupying force and the Sing-Akademie collection was presumed lost for decades until in 1999 it was revealed to be held in Kiev that's the only reason Kiev factors into this story, but the, actually so that's 20th century 19th century Leip-Zig was the center of music publishing period and that is where C.P.E. Bach's music was being published primarily in the 19th century, Johannes Brahms edited C.P.E. Bach's music, he own C.P.E. Bach autographed manuscripts, but the, and book publishing was always was strong very much in the 18th century in Leip-Zig but musically, the sort of polls in northern Germany were first and foremost Dresden and then kind of an imitation of Dresden, Fredrick the Great developed his musical establishment in Berlin, so in the latter half of the 18th century it was only in the latter half of the 18th that there was any musical life to speak of in Berlin. >> If you could wait for the microphone so we can make sure we hear your questions. >> Can you say something about the type of paper that these are on and has it been or undergone any modern conservation efforts? >> Daniel Boomhower: Yes, the paper it's all manufactured paper, mass produced paper was a phenomenon of the 19th century, so all of this is what actually, I was dying to say something about all of these hipsters in this photo, so they're people who dress like this today would be very thrilled to be craft papermakers, but just like they make Kraft beer. The handmade paper is essentially it's rag paper, it's linen, cotton, and it's the fibers are dissolved into this kind of gelatinous ooze and then it's poured over a screen and in the screens papermakers would weave their, it's a wire screen that looks not very dissimilar from window screen today, a metal not the nylon things, and into the screens would be woven often a decorative figure that would be sort of a trademark of a paper mill and it is a watermark, so the watermarks that you see in your copier paper, your fancier copier paper purely an imitation of this earlier practice and so that's how you can distinguish these different kinds of papers. The only reason conservation is generally needed on this kind of paper, is when there's corrosion from the ink, so inks were usually contained some sort of iron in them and the more iron there is the more likely oxidation will cause the ink to erode the paper or corrode the paper; otherwise, this paper is stunningly strong and it survives in much better shape than 19th century and 20th century paper. So you'll see there are numerous example and everything on display in the foyer is 18th century printed editions or manuscripts so it's all inherently 18th century paper and they're in stunningly good condition. >> I was just curious about the cost in the purchasing of these manuscripts, you mentioned 60 marks but I don't know how much that is or in today's marketplace and how valuable they might be in the marketplace today. >> Daniel Boomhower: So. >> On auction or something like that. >> Daniel Boomhower: Yeah, so it, when we shy away from talking about money cause the collections here are, if we were to buy them today would be shockingly expensive and the, but not across the board but even in like a copyist manuscript of a C.P.E. Bach concerto would not be shockingly expensive. Shockingly expensive in my mind depending on the music is 6 or 7 figures and there's definitely music that sells for that. The, 2 years ago, or about a year ago, a copy of the Goldberg variations which was published, one of the few pieces published during J.S. Bach's lifetime, sold at auction for a record for a printed piece of music I want to say it was 209,000 pounds, so that would be around 300,000 dollars but that's Goldberg variations and that J.S. Bach and they're about I don't know maybe 30 copies of the Goldberg variations that survive in the original printed edition. C.P.E. Bach, I don't know, I'm sure we could find examples of things sold recently, I would think that contemporary printed edition depending on what it was would be in the neighborhood of maybe 8 to 15,000 dollars; manuscripts it's a totally different ballgame, but it doesn't mean that that numbers are going to be significantly different it's just, you know, something worth what someone's willing to pay for it. [ Silence ] Any other questions? Well, thank you for indulging me. Like I said, it was kind of detailed material that I was laying on you. I hope you found that part of the notion of building the collections here at the library to be interesting at the very least, so thank you very much.
