Valse-scherzo, for violin and orchestra in C major, op. 34

The Valse-Scherzo in C major, Op. 34, TH 58, is a work for violin and orchestra by Pyotr Ilyich Tchaikovsky, written in 1877.
It is not to be confused with two similarly named works by Tchaikovsky, both for solo piano: one written in 1870 as Op. 7, and one from 1889 without opus number.
