The Snare drum.. The metal is the snare.
It is called a snare drum because it has wires going across the center of the drum, underneath, when the drum is struck, it uses the metal wires to create a "sizzle" or "rattle" sound. This gives it the distinct sound that a snare drum has. And some people will just call a snare drum a snare for short.
The snare drum's sound range depends on the sticks you use (there are the standard wood, plastic, and even metal tipped ones) it also depends on the tension of the head. Changing these change the sound.
The ropes are very tightly on the drum so that a system of metal rings bring the skin over the drum shell. Also the drum is hollow so that there would be sound when you hit it and vibrates with the air inside the drum.
By beating it more harder or softer.
The area in which you drum will not change the pitch but change the way in which you hear the drum. The sound may last longer or less, it may be loud or quiet.
Could be your brakes. If you have drum brakes not disk brakes that sound will happen when your shoes are worn down to the rivets. Some of the hardware such as springs, may have came off as well, which will make the loose metal sound.
it depends what kind of drum. some drums have a simple elastic band that vibrates, and a snare drum, has some metal snares, that's why its called that.
will change the sound a littlebit
a timpani's (kettle drum's) pitch is changed by adjusting a foot peddle, which tightens or loosens the heads
The drum head(s). On a snare drum, the "snare" is a set of metal wires that strap onto the bottom head and vibrate against it as it vibrates in response to the striking of the top head, creating the characteristic snare drum sound.
By playing two bass drums really fast, or one bass drum with a double pedal.
You can tune a bass drum by turning.the knobs to the right to tighten or left to loosen on the rim of the drum. Loosen it for a lower pitch, tighten for higher pitch.
