The Symphonic and Chamber Music Bank of the Ph.D. Program in Music at the Graduate School of the City University of New York is an archive of 18th and 19th century reproductions assembled with a special purpose. Pertinent parts and scores have been culled from libraries and collections world-wide, bringing a lesser-known notated music to a central location for further intensive study. The archive, which has been expanding steadily since 1974, was conceived by Professor Barry Brook, the first Executive Officer of the CUNY Music Department. It is our intent to present the compositional sources - the compositions heard in the classical salons, courts, and concert halls - which did not necessarily make their way into the current repertoire. Excluded are the bulk of the works of the masters - Haydn, Mozart, and Beethoven - which have already been catalogued extensively, and are constantly being updated. Included are any compositions from the early 1700s through the1830s which have survived. These building blocks of yesteryear are the foundation for a penetrating rediscovery and assessment of music in the Classic Era.
