The Seasons, Op. 37a, is a set of twelve short character pieces for solo piano by the Russian composer Pyotr Ilyich Tchaikovsky. Each piece is the characteristic of a different month of the year in Russia. The work is also sometimes heard in orchestral and other arrangements by other hands. Individual excerpts have always been popular – Troika (November) was a favourite encore of Sergei Rachmaninoff, and Barcarolle (June) was enormously popular and appeared in numerous arrangements.
