A pianist (US: /piːˈænɪst/ pee-AN-ist, also /ˈpiːənɪst/ PEE-ə-nist) is a musician who plays the piano. A pianist's repertoire may include music from a diverse variety of styles, such as traditional classical music, jazz, blues, and popular music, including rock and roll. Most pianists can, to an extent, easily play other keyboard instruments such as the synthesizer, harpsichord, celesta, and the organ.
