I just had a thought:
In contemporary playing there is something called 'gut-slaps' or something like that, where the diaphram is used to give a kick of air allowing the player to play in double time because the push of air out initiates a sniff in. I can't remember the other name for this but people say it is similar to saying 'ha ha ha' down the stick.
Okay!
My thought was this - does the passive voice in
traditional playing provide that as well? Is that part of the point of the passive voice? Not only does the voice provide the gravel in trad playing but perhaps it provides the force for 'the correct way of playing' (where air enters the body because of a vacuum rather than the breath and sniff used in contemporary playing)?
Perhaps you all concluded this a while ago but it just occured to me!

There as an audible clunk as the penny dropped! Seems to be logical.
Back to my practice.... Kyle gave me some of his time (and the neighbours still haven't complained, bless them) and I am trying to dirrl again! Much fun
