Percussion instruments can be classified into two categories according to the pitch:
Defined height (tuned): Those who produce identifiable notes. That is, those whose height is determined sound.
Some are the timpani, xylophone, vibraphone, bell, tubular bell, metal drums from Trinidad.
Indefinite height (not tuned): Those whose grades are not identifiable, ie produce notes indeterminate height.
Among them are: the kick, snare, drawer, afuche, castanets, keys, cowbell, cymbal, guiro, the rattle, the zambomba, the vibraslap, jaw, battery, tuntaina.
In the orchestras will usually differentiate between:

According to other criteria, can be classified into four categories which are:
Membranophones, which use a tensioned membrane or slightly loose.
Microphones, adding hit buzzer to sound.
Idiophones that ring by themselves, as the triangle.
Placófono, metal plates collide.
This classification is not strict, for example, is a tambourine idiófono membranófono and because it has both the skin and the bells.
