Tonbak

The Tompak, also tombak, donbak, dombak or zarb is a goblet drum from Persia. It is considered the principal percussion instrument of Persian music. The tonbak is normally positioned diagonally across the torso while the player uses one or more fingers and/or the palm of the hand on the drumhead, often near the drumhead's edge. Sometimes tonbak players wear metal finger rings for an extra-percussive "click" on the drum's shell. Tonbak virtuosi perform solos lasting ten minutes or more.
