25 Sketches (or Etudes) for violin and piano were composed in 1985-1987 in Minsk and Bobruisk (Belarus), but the original manuscript was confiscated or stolen, when the author was deported from his native Belarus, and was taken by force (with his family) from Warsaw to a non-European country, notoriously known for violation of international law and war crimes. Just one (Nr. 15) of all 25 pieces survived occasionally, due to a preserved draft copy. Unfortunately, all original articulation and expression remarks were lost. Some of the Sketches might be still kept by Igor Kornelyuk (author's schoolmate from Brest and friend; later famous composer in St.-Petersburg) and Dmitri Br. Smolski (leading symphonist in Belarus, author's short-time teacher). Small fragments of 3 other sketches were found among author's papers. This piece is based on the short fragment of the former Sketch Nr. 11, and was reshaped into a Trumpet in C Solo (2001), for author's friend, famous piano technician and virtuoso trumpet player. The present version is an adaptation from Trumpet Solo. Developed from a small part of Sketch 11-th draft, it gives an astonishing insight into an alternative universe of "non-conventional" thinking.
