Azari Tunable Dayereh
The Azari Dayereh that in the previous years was played by the masters was larger than the current size. But over the years manufacturers recreated it with a smaller radius. As an example, the Dayereh that "Maestro Farnam" used to play was made with an approximate diameter of 16 inches (40 cm). HaPa Drums, in order to revive this instrument with the original sonority and re-authenticatin, has produced Azari Dayereh with the same basic original size. The Remo synthetic drumheads that are used on this Dayereh with tuning capability are known as " Fish Skin”.
