The clavicymbalum (or clavisymbalum, clavisimbalum, etc.) is an early
keyboard instrument and ancestor of the
harpsichord. The instrument is described as a
psaltery to which keys, but no dampers, have been attached, allowing the keys rather than the fingers to pluck the strings, which then ring until their sound fades out. [1]
One of its earliest attestations is a 1323 work by
Johannes de Muris, where it describes a monochordium as an instrument "with a keyboard of two octaves, of triangular form, with one of the three sides curved."[citation needed]
The work of
Henri-Arnault de Zwolle (between 1438 and 1446) describes the clavicymbalum as one of the "three types" of keyboard instruments, along with the dulce melos (an early piano) and the clavicordium (
clavichord).[2]
