A harpsichord is a musical instrument played by means of a keyboard. It produces sound by plucking a string when each key is pressed.
Also in the harpsichord family is the smaller virginals, the muselar or muselaar virginals and the spinet, but not the clavichord which is a hammered instrument.
The harpsichord was widely used in baroque music. It became less popular following the invention of the piano, but its distinctive sound is still used in contemporary music.
