Re: [microsound] AI & rhythm perception - 'groove' heuristics?

[Bill Jarboe <billjarboe@xxxxxxxxxxxxx>]

 Hi Damian (and others),


   I was listening to si-cut.db (probably voluptuous midnight original 
, not the stephan m. remix) and thinking of groove as iteration of an 
event , then another iteration when it begs for reexamination , 
essentially the same iteration which is different from reiteration of 
that event. In the case of the benford tune , also some Kit Clayton , 
Run-D.M.C. It's Not Funny (from King of Rock) the event is perhaps to 
invite the observation not that it exists , more the observation i 
exist i exist i exist i exist. Any of the tunes of which I am thinking 
might seem uninteresting on the surface , yet they have their subtle 
magic. I imagine an individual on a dance floor wallowing in infinitude 
with enough boundaries to keep it friendly.

 I've also thought of backbeat as a completely unrelated sound or 
feeling , when you know the one is going to come back around and you 
comment or accomplish something in the meantime.


                                                                 -b
