Are percussion instruments that can vary in size and are used in several musical genres. Three major types of bass drums can be distinguished. The type usually seen or heard in orchestral, ensemble or concert band music is the orchestral, or concert bass drum (in Italian: gran cassa, gran tamburo). It is the largest drum of the orchestra. The kick drum, struck with a beater attached to a pedal, is usually seen on drum kits. The third type, the pitched bass drum, is generally used in marching bands and drum corps. This particular type of drum is tuned to a specific pitch and is usually played in a set of three to five drums. The bass drum was imported from the Middle East.Techniques:
The most common method of bass drum playing is a "heel-up" technique: the pedals are struck with the ball of the feet using force primarily from the thigh as opposed to the ankles when using the "heel-down" technique. Most drummers play single strokes, although there are many who are also capable of playing doubles or diddles. Drummers such as Thomas Lang, Virgil Donati, and Mike Portnoy are capable of performing complicated solos on top of an ostinato bass drum pattern. Thomas Lang, for example, has mastered the heel-up and heel-down (single- and double-stroke) to the extent that he is able to play dynamically with the bass drum and to perform various rudiments with his feet.
In order to play "doubles", proponents of the "heel up" technique use either one of two techniques: the "slide technique" or the heel-toe technique. In the slide technique, the pedal is struck around the middle area with the ball of the foot.
