Bass Drum
The bass drum is a
large drum, generally with a head on each side and is meant to produce
low frequency sounds. They are most commonly struck with some variation
of a simple padded mallet. Musically they are used either to create
a pulse, or as means of adding an accent to the music being performed.
There are three basic kinds of bass drums. The "kick," as
it's referred to on a drum set, is the smallest of the three and is
struck with a mallet attached to a foot pedal. The marching bass drum
is used primarily with marching bands and is normally found in groups
of three or four per ensemble. Each one is tuned to a specific note,
and the combination of the drums can create simple motives. The concert
bass drum is the largest of the three and is primarily used in orchestras
and symphonic wind ensembles.
As with all drums, the bass drum is a fairly simple instrument. They
are normally constructed out of wood, although new composite materials
have also been used. A skin of some kind (called a "head")
is then stretched over each side of the cylinder and tightened until
the desired tone is heard. These heads traditionally were made from
animal hide, but modern drumheads are usually made from some form of
plastic.
