The disposition of a harpsichord is the set of choirs of strings it contains. This article describes various dispositions and gives the standard notation for describing them. If a harpsichord contains just one set of strings at normal concert pitch, its disposition is called 1 x 8'. Here, the 8' means eight foot pitch, which designates normal pitch. Harpsichord makers sometimes produced ottavini, which were little harpsichords that sounded one octave above normal pitch. The disposition of an ottavino would be called 1 x 4', meaning it has one set of strings at four foot pitch.
