Andante and Finale
The Andante and Finale is a composition for piano and orchestra that was reworked by Sergei Taneyev from sketches by Pyotr Ilyich Tchaikovsky for the abandoned latter movements of his single-movement Piano Concerto No. 3 in E-flat, Op. 75. 
The core of the music is by Tchaikovsky, but the realisation was by Taneyev, and the decisions on the form, genre and title were jointly made by Taneyev, Tchaikovsky's brother Modest, Alexander Siloti and the publisher Mitrofan Belyayev. It was nevertheless
a theme, nine variations, and a finale:
1. Introduction: Allegro
2. Theme: Andante
3. Variation 1: Vivace leggero
4. Variation 2: Pesante
5. Variation 3: Moderato
6. Variation 4: Ritardando molto
7. Variation 5: Allegro misterioso
8. Variation 6: Accelerando molto
9. Variation 7: Andante
10. Variation 8: Allegro giocoso
11. Variation 9: Andante
12. Finale: Allegro molto
