I heardd this technique in a Cd, by Ash Dargan, a great aboriginal
didjplayer. I had a hard time learning it because I hadn't understood
that the TO-U is made up by a sound plus a bounce given by the breathing (U).
Actually, if - immediately after playing the TO - you circular breath, push
with the tongue and close the jaw, you'll obtain the "U" sound. I recommend to
take short sniffs on every "U". Should you like to listen to the complete
version of this song, download the 'Didjabout' CD:
