the drummer can do other things to the kit, such as attach a tambourine to the spine of the hi-hat, so when he/she puts his/her foot down on the pedal or hits it with a drumstick, the drummer gets the tambourine sound at the same time. cymbals can also have rivets inserted into them to give them a 'sizzling' sound, or a cowbell can be attached to the top of the bass drum between the snare and floor tom to use in fills, solos, grooves, etc.
