Drum (638 words) |
 | Drums consist of at least one membrane, called a drumhead or drumskin, that is stretched over a shell and struck, either directly with parts of a player's body, or with some sort of implement such as a drumstick, to produce sound. |
| The message-sending logs are not drums at all from the technical point of view, since they do not have a skin or membrane that would vibrate as they are beaten. |
| The drum often has a narrow neck between the drum heads, across which stretch the sinews holding the skins; the drum will be held under one arm, which is squeezed down on the sinews to vary the tension in the drumheads and therefore the pitch of the sound. |
