Clarichord
An old variety of the harpsichord.
Clarinet or Clarionet (a little clarion). A wind instrument with a beating reed, invented in 1654 by Denner. The compass of the clarinet is from E third space bass to the second C above the treble (the highest octave is rarely used). Clarinets are made in several keys; those used in the orchestra are in C, Br and A; the Bb clarinet sounds a whole tone lower than the written notes, the A clarinet a minor third lower; alto and bass clarinets are also used, the former in Fand Eb, the latter an octave below the ordinary clarinet. The clarinet has four well-marked registers: the first, or chalumeau, extends from the lowest note to the octave above; second to Bb in treble staff; third to C above treble staff; fourth the rest of the compass.
