Modern Instruments - Percussion
A percussion instrument is any object which produces a sound by being hit with an implement, shaken, rubbed, scraped, or by any other action which sets the object into vibration. The term usually applies to an object used in a rhythmic context or with musical intent. Of all the instrument families in use in today’s music, the only family that is consistently adding new instruments every year is the percussion family. There are two types of percussion instruments: pitched and non-pitched instruments.
Pitched instruments include the timpani, glockenspiel (Concert Bells), xylophone, vibraphone, marimba, and numerous other examples.
Non-pitched instruments include the snare drum, bass drum, cymbals, triangles, whistles, and numerous other examples.
