The piccolo's compass extends three octaves upward from the second D above middle C. Its orchestral use dates from the late 18th century, when it replaced the flageolet (also called flauto piccolo). A six-keyed piccolo in D♭ was formerly used in military bands to facilitate playing in flat keys. Piccolo is also the name of an organ stop; the word can be applied to other instruments, such as the piccolo clarinet or the violino piccolo (“small violin”).
