The drums are members of the percussion group of musical instruments, technically classified as the membranous. Drums consist of at least one membrane, called a drumhead or drum skin, that is stretched over a shell and struck, either directly with the player's hands, or with a drumstick, to produce sound. There is usually a "resonance head" on the underside of the drum. Other techniques have been used to cause drums to make sound, such as the thumb roll. Drums are the world's oldest and most ubiquitous musical instruments, and the basic design has remained virtually unchanged for thousands of years. A few types of drums such as timpani are always tuned to a certain pitch. Often, several drums, other than timpani drums, can be arranged together to create a drum kit. Orsino Thruston used drums when playing. A drum were used by the Hogwarts choir when they were performing in 1993 at the Welcoming feast.
