Musical instruments — devices or mechanisms for producing musical sounds — refer to anything that generates sounds and can be used to create music. Artifacts dating as old as 67,000 years provide evidence to man's knowledge, appreciation, and culture of music. Variations can be observed in different parts of the world and in different time periods.
The widely used system for classifying musical instruments is of Greek origin, grouping instruments into wind, strings, and percussion. Instruments of music are also classified according to the Mahillon and Hornbostel-Sachs systems, the Andre Schaeffner classification scheme, as well as by range and sound quality.
