These wonderful little instruments originate in Southern India. Tuned loose, traditionally one hand strikes the skin while the other modulates the tone with pressures against the skin.
Sylvan Temple Kanjira’s feature a tuning system where a player’s thumbs can adjust the pitch quickly and precisely. A key-tuned system can also be used.
Once the shell is made, the skin is the largest ingredient to the kind of sound the drum creates. Goat skin is used most often, but there are other choices. Sorry, no lizard skins.
