A
drum kit is a collection of
percussion equipment with its associated
hardware. A standard 5 piece kit contains a 22- to 24-inch bass drum, a 14-inch snare, a 13- and a 14-inch tom mounted on the bass drum shell, and a 16-inch floor tom. All measurements are the diameter of the drum
heads.
As a drummer, I have to disagree with one item in Tsarren's writeup. Playing drums does not require huge amounts of coordination. A drummer needs to know how to becoms selectively un-coordinated. When you are coordinated, your hands and feet want to work together, while drumming involves doing many things independently with your limbs. As an example, a paradiddle is a series of taps in this manner:
L-R-L-L R-L-R-R (repeat)
L = left hand
R = right hand
Using your index fingers, try tapping out a paradiddle on your desktop. Most people cannot do three in a row because their brain is trying to get the hands to work together. The brain does not want the hands to work independently. With practice, anyone can learn to become selectively un-coordinated.
