The Tombak drum, also known as the tonbak, is a traditional Persian percussion instrument made from a single piece of wood. It has a goblet shape, allowing for a variety of sounds and rhythms. The drum is typically played with the hands and is an essential part of Persian music, often accompanying other instruments. Tombak drums are known for their versatility and can be used in various musical genres, from classical to contemporary. Musicians can produce different tones by striking different areas of the drumhead, making it a dynamic instrument in both solo and ensemble performances.
