Johann Christoph Friedrich Bach, German harpsichord player and composer (born 1732)

Johann Christoph Friedrich Bach was a German composer and harpsichordist, the fifth son of Johann Sebastian Bach, sometimes referred to as the "Bückeburg Bach".

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.
