Dmitri Shostakovich’s Music for Chamber Ensembles.

To the Memory of V.I. Kurchavov
Two Pieces
For String Octet. Op. 11. 1924-1925.

  This edition is based on the publication of the score of Two Pieces in Volume 37 of Dmitri Shostakovich’s Collected Works, Muzyka Publishers, Moscow, 1983 (S-83). The following are taken into account: author’s manuscript of the score in the first version (A1), author’s manuscript of the score in the second, final version (A2), as well as the last publication of the score of Two Pieces during the composer’s lifetime, Muzyka Publishers, Moscow, 1967 (S-67).
  In several episodes, A1 differs significantly from both A2 (which is relatively close to the printed editions), and from S-67 and S-83. These differences include different rehearsal numbers, fundamentally different dynamic and articulation marks or their complete absence, different arrangement of the music according to parts, and so on. In this respect, the differences between A1 and this edition are only stipulated in the comments when A1, A2, S-67 and S-83 are compared in controversial episodes, while the designations in A1 that are not included in A2, S-67, or S-83 are only mentioned in the comments when such designations are used in this edition. In turn, all the notation peculiarities of A2 are specified in the comments.
  In S-83, some of the editorial signs are given in square brackets. In this edition, the square brackets are removed when using these signs in the score, and their absence is not specified in the comments. Obvious slips of the pen in S-67 and S-83 are corrected without qualification.
  The score of Two Pieces in this version is published in a separate edition, DSCH, Moscow, 2015 (S-2015). Small changes that appeared in this edition during editing and were made after S-2015 came out are specified in these comments.
