The 24 Preludes and Fugues, Op. 87 by Dmitri Shostakovich are a set of 24 musical pieces for solo piano, one in each of the major and minor keys of the chromatic scale. The cycle was composed in 1950 and 1951 while Shostakovich was in Moscow, and premiered by pianist Tatiana Nikolayeva in Leningrad in December 1952; it was published the same year. A complete performance takes approximately 2 hours and 32 minutes. It is one of several examples of music written in all major and/or minor keys.
Notes; I have only played the Prelude here as the fugue gets rather interesting.
This long double fugue shares a key signature and several features with and references to the final fugue from Bach's The Art of Fugue. The first subject. hinted at in the prelude, is introduced quietly, but the fugue speeds up when the second subject is introduced, and forceful final notes, an extended Picardy third that recalls the triumphant end of the Fifth Symphony conclude the piece and the cycle. This fugue uses just about all the contrapuntal resources available: double stretto, cancrizan, augmentation, diminution, pedal point and invertible counterpoint.
There are a few more that might transfer to the organ. Score attached below.
We are lucky to have a recording of them all played by Tatiana Nikolayeva here with the score;

Of interest Olli Mustonen recorded the Shostakovich preludes and fugues in conjunction with those by Bach in sequences that contrast these works. His first recording was issued by RCA Victor Red Seal in 1996 and the second by Ondine Records in 2002.
