The presence of Hamparsum sheet music and original sheet music in the collection written by Kemal Batanay (1893-1981), a composer of Turkish music and ta‘līḳ calligrapher, makes this archive valuable. The collection mostly consists of rare works written by musicians. Among the most prominent documents in the archive are 1,342 pieces of sheet music written in Kemal Batanay’s own handwriting, 789 printed and 860 photocopied sheet music, 55 original and photocopied notebooks, and 396 compilations. The collection, which covers the dates when the owner of the collection lived, is organized in 30 folders and 2,137 files.
UntitledCüneyd Kosal (1931-2018) is an important kanun (zither) player and composer who grew up in the last periods of classical Turkish music and has the title of the largest collector in his field with his extensive archive of sheet music that he meticulously compiled over 65 years. In addition to contributing to the publication of the notes of classical works within the Ministry of National Education, he restored and notated hundreds of works, of which only sound recordings have survived to the present day, and brought them into the repertoire of Turkish religious music.
The archive, which is among the most important written sources of Turkish music today, contains nearly 83.000 pieces of sheet music, 182 manuscript notebooks and retail copies of sheet music, and 478 books and journals on Turkish music. The 7,428 works in 182 manuscript notebooks have been cataloged and opened for research.
