"The Tompak (official Persian name) (\u062A\u0646\u067E\u06A9, \u062A\u0646\u0628\u06A9, \u062F\u0646\u0628\u06A9\u060C \u062A\u0645\u067E\u06A9), also tombak, donbak, dombak or zarb (\u0636\u064E\u0631\u0628 or \u0636\u0631\u0628) is a goblet drum from Persia (ancient Iran). 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(s) of the hand(s) on the drumhead, often (for a ringing timbre) near the drumhead's edge."@en . .
