Compass and pitch range

On the whole, earlier harpsichords have smaller ranges than later ones, although there are many exceptions. The largest harpsichords have a range of just over five octaves, and the smallest have under four. Usually, the shortest keyboards were given extended range in the bass with a " short octave ". The traditional pitch range for a 5-octave instrument is F –F (FF–f‴).

Tuning pitch is often taken to be A = 415 Hz, roughly a semitone lower than the modern standard concert pitch of A = 440 Hz. An accepted exception is for French baroque repertoire, which is often performed with a = 392 Hz, approximately a semitone lower again. See Jean-Philippe Rameau 's Treatise on Harmony (1722), Book One, chapter five, for insight into French baroque tuning; "Since most of these semitones are absolutely necessary in the tuning of organs and other similar instruments, the following chromatic system has been drawn up." Tuning an instrument nowadays usually starts with setting an A; historically it would commence from a C or an F. The harpsichord uses the bass clef (F clef).

Some modern instruments are built with keyboards that can shift sideways, allowing the player to align the mechanism with strings at either A = 415 Hz or A = 440 Hz. If a tuning other than equal temperament is used, the instrument requires retuning once the keyboard is shifted.
