Ektara
In origin the ektara literally "one-string" was a regular string instrument of wandering bards and minstrels from India and is plucked with one finger. The ektara usually has a stretched single string, an animal skin over a head (made of dried pumpkin/gourd, wood or coconut) and pole neck or split bamboo cane neck. The various sizes of ektara are soprano, tenor, and bass. The bass ektara, sometimes called a dotara often has two strings (as literally implied by do, "two").
