Lombok drum - Lafforgue

The drum is a member of the percussion group of musical instruments, which is technically classified as the membranophones. 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 drum stick, to produce sound. There is usually a "resonance head" on the underside of the drum, these are usually tuned to a slightly lower pitch than the top drumhead. 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.

Lombok is an island in West Nusa Tenggara (Nusa Tenggara Barat or NTB) province, Indonesia. It forms part of the chain of the Lesser Sunda Islands, with the Lombok Strait separating it from Bali to the west and the Alas Strait between it and Sumbawa to the east. It is roughly circular, with a "tail" (Sekotong Peninsula) to the southwest, about 70 km across and a total area of about 4,725 km² (1,825 sq mi). The provincial capital and largest city on the island is Mataram. It is somewhat similar in size and density with neighboring Bali and shares some cultural heritage, but is administratively part of NTB along with sparsely populated Sumbawa. It is surrounded by a number of smaller islands locally called Gili.

The island is home to some 3.16 million Indonesians as recorded in the decennial 2010 census, and in 4 regencies along with the provincial capital Mataram.
