Percussion is basically all the instruments you hit/involve hitting

Drums (and all classes of them including things like bongos, bass drums, congas, timpanis,  etc.), Tambourine, Sleigh Bells, Cowbell, Chimes, Marimba (and all the mallet instruments like vibraphone, glockenspiel, xylophone, etc.), Harp, Steel Pans (look it up they're heccing cool), ...

Basically, there's a lot of instruments that fall under it

And Piano is one of them, though sometimes disputed

have fun responding to this
