An idiophone is any musical instrument that creates the sound primarily by the instrument as a whole. Vibrating with out the use of strings or membranes. The early classification of Victor-Charles Mahillon called this group of instruments autophones.
Most percussion instruments that are not drums are idiophones. Hornbostel-Sachs classifies idiophones into four main sub-categories. The first division is the struck idiophones, sometimes called concussion idiophones.
This includes most of the non-drum percussion instruments familiar in the West. They include all idiophones made to vibrate by being struck, either directly with a stick or hand like the wood block, singing bowl, steel tongue drum, triangle or marimba or indirectly, by way of a scraping or shaking motion (like maracas or flexatone). Various types of bells fall into both categories.
