cembalist

1. (historical) An orchestral keyboard player; one who plays piano or harpsichord for an orchestra or ensemble.Examples: "Ensemble performances were led by the organist or cembalist ; he sat at his instrument, played the “accompaniment,” and directed the performance—now by movements of his head, now perhaps by beating time with one hand."; "While the symphonies of Haydn and Mozart could conceivably be played fairly acceptably under the dual leadership of concertmaster and cembalist, the symphonies of Beethoven could not."; "The position of cembalist was one of equal honor and responsibility."historical
