（Music.) An instrument of the viol family, the low octave of the violoncello. It has three strings tuned in fifth and fourth. It has movable keys to press the strings upon frets of the neck. The keys are moved by levers governed by the left hand, and by pedal keys on which the foot of the player acts. Its compass is one octave and a fifth.

1877.
