Collaborative piano is a discipline of music that combines piano performance, accompaniment, and music pedagogy (and often, vocal coaching).

Genres

Instrumental literature 
One responsibility of the collaborative pianist is to perform the piano part of the instrumental sonata literature. These are duo chamber works, and the role of the pianist in this genre is that of equal partner with the instrumentalist. This includes a large number of works such as but not limited to the following important works from the string repertoire:

 Wolfgang A. Mozart, Sonatas for Piano and Violin
 Ludwig van Beethoven, 10 Sonatas for Piano and Violin, 5 Sonatas for Cello and Piano
 Franz Schubert, 3 Sonatinas for Violin and Piano, et al.
 Robert Schumann, 3 Sonatas for Violin and Piano
 Cesar Franck, Sonata for Violin and Piano
 Johannes Brahms, 3 Sonatas for Violin and Piano, 2 Sonatas for Cello and Piano, 2 Sonatas for Clarinet (or Viola) and Piano
 Edvard Grieg, 3 Sonatas for Violin and Piano, Sonata for Cello and Piano
 Gabriel Fauré, 2 Sonatas for Violin and Piano, 2 Sonatas for Cello and Piano
 Claude Debussy, Violin Sonata, Cello Sonata
 Richard Strauss, Violin Sonata, Cello Sonata
 George Enescu, 3 Sonatas for Violin and Piano, 2 Sonatas for Cello and Piano
 Sergei Prokofiev, 2 Sonatas for Violin and Piano, Sonata for Cello and Piano

In addition to sonatas, the instrumental collaborative piano literature includes short pieces, often of a virtuoso nature. In this genre, the original work is often for a soloist with orchestral accompaniment; but in order to enable the work to be performed under wider circumstances, composers often also write piano reductions of the orchestral score.

Another important responsibility of the collaborative pianist is to perform the accompaniment of other, multi-movement non-chamber works such as concertos. In this role, the collaborative pianist is often serving as a rehearsal partner for the study of this extensive repertoire as preparation for the instrumentalist's subsequent performance with orchestral accompaniment.
