The drum kit is a very important percussion instrument in the jazz band. It usually consists of a bass drum (also known as "kick drum"), a snare drum, two or more Tom-Tom Drum, one or two Crash Cymbal, a Ride Cymbal and a hi-Hat with pedals. At the same time, each instrument should be equipped with a special microphone for pickup.
The kick drum is the bass part. Generally used with a more durable dynamic microphone ,which directivity is the cardioid and the frequency response range is relatively low. The position is placed on the back of the kick drum (front side according to the hit side), slightly off center. Some drummers will remove the bottom drum skin on the back or cut the drum skin into a small opening and put the microphone in.
