This is a bhawaiya (Northern) Bengali dotara that you see played by the Baul people (wandering minstrels of Bengal) and Rajbongshi people. This northern Bengal / Assamese style has round shaped resonator and minimalist look. Goat skin covers the resonator and steel strings are used. The tonic note this was made for is C (though, it go up or down in pitch). The strings are tuned to pa, sa, sa, ma (in Indian music notation). The bridge is made of sheesham. A nice feature is that it has very stable tuning machines. It has a sunmica fingerboard, which is popular in Bengal and produces a good tone with low friction. The wood is Indian mahogany. It has a brass tailpiece. I ship it detuned and with the bridge on its side to prevent pressure on the skin. I can answer any questions about putting the bridge up right and tuning. I will include a traditional coconut shell plectrum, the strap, and a brand new dotara bag.
