A common sub-classification of percussion instruments that is comprised of "toys" or special sound effects. Some of these instruments are tuned (able to produce a specific pitch) and others are untuned (unable to produce a specific pitch), but all of them are notated without specific pitches. Their main function is to provide a sound that is either comical or meant to simulate a known sound.
Auxiliary percussion instruments include:
