Twenty-Four Preludes - Op. 20
Twenty Four Preludes, Op. 20
First published in USSR in 1934 (Triton Edition).
Various individual preludes have been included within sheet music compilation books, see for example: Catalog record from Russian State Library, five preludes included in set.
Prelude No. 3 in C# Major, taken from the 1934 Triton (USSR) Edition
Ostensibly the first of Zhelobinsky's instrumental compositions to see active publication, as no published editions have been located which would predate this set of preludes (though autographs of earlier scores do exist).
