I successfully crafted an Arabic bamboo flute which plays Key E in Arabic Scale. Sorry for the "blackened" video. Nevertheless, the audio is quite distinctive. All tone holes are predefined to play the right notes which comprises the Arabic Scale. The base note is E in 4th octave (Key E4). I also attached some of the snap shots of the flute for your kind appreciation. Notice the placement of the tone holes and the size of each of them. It is comprised of 6 tone holes like its Major Scale counterpart with the difference in placements. I hope you enjoy it , and if for some reason, I am contactable at firstname.lastname@example.org or +60193827279.
