How are different sounds made on the bongo drums?
“The size of the drums also has an effect on the sound that is generated. The smaller drum tends to produce higher notes than the larger drum. This is because the smaller head is under greater tension, and because the body of the drum is smaller, thus affecting the speed of the sound waves. Bongo sets themselves can range in size, though they generally fit between the knees of the player.” Weather also plays a role in the pitch of the bongo drum. If your drum pitch is sharp, add a little moisture to your natural skin bongo. You can also warm them up to get a different sound when you strike the head.
