Anton Arensky
Variations on a Theme by Tchaikovsky, Op. 35a, a piece for string orchestra by Anton Arensky, started out as the slow movement of his String Quartet No. 2 in A minor, Op. 35, for the unusual scoring of violin, viola, and 2 cellos. It was written in 1894, the year after the death of Pyotr Ilyich Tchaikovsky, in a tribute to that composer. It is based on the theme from the song "Legend", the fifth of Tchaikovsky's "Sixteen Children's Songs", Op. 54.
