HOW TO MIC A SNARE DRUM
The snare drum consists of several large sound sources.
The batter (top) head produces the main tone and overtones. The rim, which is often played by itself (e.g. cross stick) or together with the batter head, produces a so called rim shot. And if the drummer is using brushes, the entire surface of the drumhead is played. The snare (bottom) head with the snares strained over.
HOW TO MIC A BASS DRUM
The bass (kick) drum is the largest sound source of the entire drum kit and also the one with the lowest frequencies.
The sound of the bass drums differs a lot with the drummer’s choice of size, heads, tuning, muffling and whether or not there is a hole in the front head. Typically, a more jazz-oriented drummer will choose a smaller size (down to 18" or smaller), thin heads and high-pitch tuning.
