The Little Rifleman
The Little Rifleman (Стрелочек) (TH 197 ; ČW 436)  is a Russian folksong on which Tchaikovsky devised a humorous canon with friends in December 1882. Its origins were described shortly afterwards in a letter from Sergey Taneyev to Anton Arensky:
"After dinner, we occupied ourselves with writing a canon on a theme, given to us by Laroche: "The Little Rifleman". He was sure that it would be hard to come up with a canon in any interval other than the octave [...] I responded that it was not so difficult, and straight away wrote a canon within a few seconds [...] This prompted Pyotr Ilyich to join the contest, and for his part he offered up a remarkable canon in no time at all [...] The whole canon was immediately performed by Laroche and Tchaikovsky. Laroche couldn't think of anything; on his bit of paper he had only written a clef and 2 flats" .
Tchaikovsky's score has not been preserved .
