(English, Quintet), in music, a composition for five voices, or for five instruments, each of which is obligato. The remarks that have been made upon the construction of the quartetto apply generally to that of the quintetto. Amongst the finest instrumental quintettes are those of Boccherini, Mozart, Beethoven, and Onslow. The best that have been composed for wind-instruments only, are A. Reicha's for flute, oboe, clarinet, horn, and bassoon.
