Thanks for the plug Alison.It really isn't difficult. I have to breath so I figure why not make some musically useful sounds while doing it.
Rhythmically I do cheat however. The didge rhythms are closely associated with my other rhythms being played on the kit. But that is the kit drummers trick. All the rhtyhms being on all limbs always have a common reference point.
Limb independance and ambidexterity and circular breathing all look and sound much more dificult than they are in practice. Mystique removed.
So now I only owe you $25 Alison.
