ORCHESTRINO, a modern musical instrument, so called by its inventor Poulléau. It was shaped like a pianoforte, had similar finger-keys, and its sounds were produced by the friction of a circular bow upon the strings. It imitated the tones of the violin, the viola, the violoncello, the viol d'amour, the double-bass, &c. The construction of the bow (of hair, &c.) is said to have been very curious and ingenious. (G. F. G.)
