The Instruments of the Drum set.
We tend to think of the drums as a single instrument. In fact it is a collection of percussion instruments. Those drums and cymbals that now, and in the past, can be played as individual instruments. We can still see snare drummers drumming in a parade band. See someone playing toms or bass drum in a marching band and see an orchestral percussionist clap two cymbals together at the end of a crescendo!
