I.S. Bach. Fugue Es-dur from Volume II of the Well-Tempered Clavier
The pieces are part of the incomplete collective collection of Shostakovich, G.L. Klements and P.E. Feldt. Judging by the extanted manuscript, their joint idea of creating twenty-four preludes in all keys was partially realized. Of the 18 pieces in the collection, Shostakovich owns No. 2–4, 15, and 18, presumably written in 1921. The same year also marks the end of work on the cycle Eight Preludes Op. 2, which, as is commonly believed, included these pieces.
However, it is safe to determine the chronological primacy of the collective collection or the opus cycle. 2 is difficult. As part of the cycle op. 2 Prelude No. 2 is set out in the mixolidian fret G. The incomplete collective manuscript was kept by G.Ya. Yudin, who in the 1980s passed it to I.A. Shostakovich. These Five Preludes were published in 1966 by L.V. Danilevich as a separate cycle (with numbering of plays 1–5). It appears in later reference editions, however, Shostakovich himself never considered these pieces outside the Op. 2.
