Percussion instrument
Drum kits can include bass drum, side drum, tom-toms, cowbells, cymbals (suspended and hi-hat) etc. Together with a string bass (double bass) they will form the “rhythm section” of a jazz group. A percussion player has to have a very good sense of rhythm. The other players rely on him or her to keep a steady beat and not to play so loudly that the others cannot hear the tune.
