Hey! I hope you see this, and I hope this will help, but I've been practicing a simple and clean by ear.
The notes are like this: {E B, AGF# G, x2}{DDDD GF#G} c,bagab, dca,gga,cb,de, d bcagf#
^ simple and clean is the_way^
f=low octave (d,e,f#,g,a,b,c,D) low D through medium d, and
f=high octave (D and above) higher than a medium D.
