Piano Concerto No. 4 in C minor, Op. 44 by Camille Saint-Saëns, is the composer's most structurally innovative piano concerto. In one sense it is structured like a four-movement symphony, but these are grouped in pairs. That is, the piece is divided into two parts, each of which combines two main movements (I. A moderate-tempo Theme and Variations in C Minor; II. A slower, related Theme and Variations in Ab Major; III. Scherzo in C Minor; IV. Finale in C Major).
