The piccolo ( PIH-kə-loh; Italian for 'small') is a half-size flute and a member of the woodwind family of musical instruments. Sometimes referred to as a "baby flute" the modern piccolo has similar fingerings as the standard transverse flute, but the sound it produces is an octave higher. This has given rise to the name ottavino (Italian pronunciation: [ottaˈviːno]), by which the instrument is called in Italian and thus also in scores of Italian composers.

Piccolos are often orchestrated to double the violins or the flutes, adding sparkle and brilliance to the overall sound because of the aforementioned one-octave transposition upwards. The piccolo is a standard member in orchestras, marching bands, and wind ensembles.
