There are optional drums that enable the drummer to expand their repertoire beyond what is possible with the more basic drum set, then there are the essential drums that no drummer would want to be without. The snare drum is an essential drum. It is widely thought of as the most important drum in a drum sets, or at least one of the most important drums in a set.
The snare drum is designed with strands of metal wire, metal or plastic cable, or gut cords that are stretched over the drumhead portion of the drum. These strands, or snares are usually located on the bottom of the drum. Certain styles of music, such as pipe and tabor and military music, include a second set of snares inside the drum under the top drumhead for a crisper sound.
The sound of the snare drum can be made stronger or softer depending on what it is being hit with. Hitting it with a drumstick will produce a stronger sound than hitting it with brush for example. The sounds produced by a snare drum also depend on if the drummer is striking the head of the drum, the rim of the drum or the shell.
