Tablas are hand drums that comes by pair which the 2 skins are (nearly) horizontally oriented with the hand moving from top to down, while mridangam/pakhawaj/dol/dolak are hand drums which the 2 skins are mounted on the opposite side of a single drum and are vertically oriented with the hand moving from left to right (or right to left):
Both have a similar way of playing as compared to other hand drums around the world, however there is a 90° hand-rotation difference between the two.
Pakhawaj (vertical skin) are known to be the Tabla's (horizontal skin) ancestor. I am wondering which one is the most suitable ergonomically speaking for such percussive movements?
What are the consequences of these two configurations in the playing? Does one facilitate specific movements for which it would be more difficult/tiring with the other one?
The two extreme positions are pronation (hand palm facing down) and supination (hand palm facing up), then the vertical position seems to be the rest position. . Then horizontal playing is a priori not the "natural position" for the human body because it requires a 90° rotation of the arm ("pronation"). Does it mean that tabla players have more health issues related to their playing than pakhawaj/mridangam players?
