Ivan Wyschnegradsky was born in 1893. He was a student of Nicholas Sokoloff at the St. Petersburg Conservatory. Wyschnegradsky made his home in Paris from 1920 until his death in 1979. He devoted most of his life to experimentation with quarter tones and other microtones and had a quarter tone piano built for his use in the 1930s. Later, he wrote for two to four pianos tuned to give the microtonal effects he desired.
SERIES I - WRITTEN MATERIALS
This series comprises books, journals, articles and analytical materials relating to Ivan Wyschnegradsky and microtonal composition.
SERIES II - CONCERT PROGRAMS OF MICROTONAL WORKS
SERIES III - CORRESPONDENCE
SERIES IV - SCORES
This series contains scores of works by Wyschnegradsky (beginning with 101), Mildred Couper (beginning with 201) and Alan Hovhaness (301). The largest part of this series is comprised of different versions of Wyschnegradsky's Preludes, Op.22 (101) about which I.W. and John Dierks shared a lengthy correspondence (see Series III). In addition to the 1977 published score (A) of these pieces, the collection contains proofs (B) sent by C.F. Peters to J.D. preceding the work's publication, photocopies (C) of the unpublished (manuscript) preludes seny by I.W. to J.D. beginning in 1973, and photocopies (D,E, numbered) made by J.D. for study and performance. Unfortunately, it is not always clear which photocopies were made and sent by I.W. and which were made by J.D. (For example, it is not certain that all of the copies found in 101 (C) were made by I.W.)
