A harpsichord is a keyboard instrument, similar to a piano, that  has an array of strings plucked by a device called a plectrum (or  pick), which is actuated by mechanisms â¦ attached to the keys.  Historically, plectrums were made of quill, but today they are  mostly made of plastic.
Harpsichord designates the whole family of similar plucked keyboard instruments, including the smaller virginals, muselar, and spinet. The harpsichord was widely used in Renaissance and Baroque music. During the late 18th century, it gradually disappeared from the musical scene, with the rise of the piano.
