The intention of the instrument is to yield clusters of sounds or noises, and not to let individual strokes be perceived 112.1 Shaken idiophones or rattles The player executes a shaking motion 112.11 Suspension rattles Perforated idiophones are mounted together, and shaken to strike against each other 112.111 Strung rattles Rattling objects are strung in rows on a cord Necklaces with rows of shells 112.112 Stick rattles Rattling objects are strung on a bar (or ring) Sistrum with rings 112.12 Frame rattles Rattling objects are attached to a carrier against which they strike 112.121 Pendant rattles Rattling objects are hung from a frame Dancing shield with rattling rings 112.122 Sliding rattles Non-sonorous objects slide to and fro in the slots of the sonorous object so that the latter is made to vibrate; or sonorous objects slide to and fro in the slots of a non-sonorous object, to be set in vibration by the impacts Anklung, sistrum with rods 112.13 Vessel rattles Rattling objects enclosed in a vessel strike against each other or against the walls of the vessel, or usually against both. NB The Benue gourd rattles with handle, in which the rattling objects, instead of being enclosed, are knotted into a net slipped over the outer surface, count as a variety of vessel rattle Fruit shells with seeds, ‘pellet bells’ enclosing loose percussion pellets 112.2 Scraped idiophones The player causes a scraping movement directly or indirectly: a non-sonorous object moves along the notched surface of a sonorous object, to be alternately lifted off the teeth and flicked against them; or an elastic sonorous object moves along the surface of a notched non-sonorous object to cause a series of impacts. This group must not be confused with that of friction idiophones 112.21 Scraped sticks A notched stick is scraped with a little stick 112.211 Scraped sticks without resonator S.
