A pianist performs on the piano, one of the most versatile instruments in Western music. The role spans from solo recital performance to accompaniment, chamber music, jazz improvisation, and orchestral playing. Classical pianists interpret works by composers such as Chopin, Liszt, Beethoven, and Rachmaninoff, requiring mastery of dynamics, pedalling, and articulation. Jazz pianists use voicings, comping, and improvisation over chord progressions. The pianist's ability to play melody and harmony simultaneously makes the piano a self-sufficient instrument, equally at home as a solo instrument or leading an ensemble. Concert pianists typically begin training in childhood and develop extraordinary finger independence and sight-reading ability.
