I will try to pass on to you how I learned on my own.
First how to tune the four strings of the dotara. Use a chormatic pitch pipe or electronic tuner. They are different tuning techniques. I tune as follows.
Start with the BASS string (the thick string nearest to you). Tune it to G sharp.
Next, tune the two middle strings. Tune them both to C sharp.
Finally, tune the high string, the one furthest from you, to F sharp.Your tuning is complete. Let me know if this helps.
Loved the song. The conditions are same or worse than what the song says in the Jute Mills of Bangladesh today. A shiftie earns Tk150 (just over a pound) for an eight hour shift.
Diptanshu, I tune my dotara strings as follows: the first string (inner) G sharp. The middle two strings C sharp and the outer string F sharp. Can you please tell me how you tuned your dotara;s four strings? It seems that you tuned the middle two stings differently. Am I right? Thanks.
@ The Busy Teacher. Thanks for listening to this song, which must be foreign to you , and commenting on it. The singer, who did not take up singing as her profession, is the grand daughter of Bengali legendary folk singer Abbasuddin Ahmed & aunt of a to be a famous singer, now studying at Berklee, Armeen Musa. Listen to Armeen's song "Bhromor koiyo giya" on youtube. Yes, the young voice at the end is that of the then six year old sister of the singer in in this clip.
