Chordophone, any of a class of musical instruments in which a stretched, vibrating string produces the initial sound. The five basic types are bows, harps, lutes, lyres, and zithers. The name chordophone replaces the term stringed instrument when a precise, acoustically based designation is required.
AEROPHONE
An aerophone is a musical instrument that produces sound primarily by causing a body of air to vibrate, without the use of strings or membranes, and without the vibration of the instrument itself adding considerably to the sound.
PERCUSSION
A percussion instrument is a musical instrument that is sounded by being struck or scraped by a beater including attached or enclosed beaters or rattles struck, scraped or rubbed by hand or struck against another similar instrument.
