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.
Technically, there are two other standard orchestra members that are also stringed instruments: the harp and the piano. While the violin family instruments are typically played using a bow, the harp is a plucked string instrument, and the piano is a hammered string instrument.
