Serenade for Strings in C major, Op. 48

Tchaikovsky intended the first movement to be an imitation of Mozart's style, and it was based on the form of the classical sonatina, with a slow introduction. The stirring 36-bar Andante introduction is marked "sempre marcatissimo" and littered with double-stopping in the violins and violas, forming towering chordal structures. This introduction is restated at the end of the movement, and then reappears, transformed, in the coda of the fourth movement, tying the entire work together.
