Piano Concerto No. 4 (Rachmaninoff) - Form

Form

Compared with its predecessors, the Fourth Concerto contains sharper thematic profiles along with a refinement of textures in keyboard and orchestra. These qualities do not lead to greater simplicity but to a different sort of complexity. It was also a continuation of Rachmaninoff's long-range creative growth: the Third Concerto and the recomposed First Concerto were less heavily orchestrated than the Second Concerto. In keeping with its general character, the Fourth Concerto is lighter still, yet more oblique.

The concerto is in three movements:

1. Allegro vivace (G minor)
2. Largo (C major)
3. Allegro vivace (G minor → D-Flat Major → G major)

Rachmaninoff had already been making a more extensive use of short thematic motifs and strong rhythmic patterns in his Op. 32 Preludes, in place of what was called the "unmentionable restlessness" that made his work, especially the concertos, a distressing experience for some musicians. This refinement of musical language, especially in orchestration, went back at least to The Bells and a more astringent tone was already noticeable in songs like "The Raising of Lazarus", Op. 34, No. 6.
