Ralph Kirkpatrick, American harpsichord player and musicologist (died 1984)

Ralph Leonard Kirkpatrick was an American harpsichordist and musicologist, widely known for his chronological catalog of Domenico Scarlatti's keyboard sonatas as well as for his performances and recordings.

A harpsichord is a musical instrument played by means of a keyboard. Depressing a key raises its back end within the instrument, which in turn raises a mechanism with a small plectrum made from quill or plastic that plucks one or more strings. The strings are under tension on a soundboard, which is mounted in a wooden case; the soundboard amplifies the vibrations from the strings so that the listeners can hear it. Like a pipe organ, a harpsichord may have more than one keyboard manual and even a pedal board. Harpsichords may also have stop levers which add or remove additional octaves. Some harpsichords may have a buff stop, which brings a strip of buff leather or other material in contact with the strings, muting their sound to simulate the sound of a plucked lute.
