Bass drum
Deep, double-headed drum of large diameter.
What it means
The bass drum is a deep drum of large diameter with two heads stretched over a cylinder. It is struck with a padded beater and produces a deep, dull sound without definite pitch.
Musical use
In the orchestra the bass drum sets accents and dramatic climaxes, produces thunder, and supports the bass. Its use in European art music was prompted in the 18th century by Turkish military music, the Janissary music, and used for instance in Mozart's The Abduction from the Seraglio. In wind bands and march music it sets the basic beat, and in the drum kit it corresponds to the kick drum.
The bass drum should be distinguished from the timpani, which are tuned to definite pitches and have a single head over a kettle, and from the snare drum with its bright, sharp sound and snares. It also differs from the bass drums of other cultures, such as the dundun, in build and manner of playing.
Performance practice
Strike the bass drum with a loose wrist and let the beater rebound at once after the stroke so that the head vibrates freely. Watch the point of striking, usually just off the center, and damp with the hand or knee when needed so the sound does not ring on.
