Just ran across this; and since a lot of you are into rhythm, I thought you might find this interesting.  Metronomes

Really cool ...I didn't expect to be watching something like that 2 min. ago .
 So if my band played on a suspended stage we might be tighter ?  ; )
 (my guitarist would be like that last blue metronome...always the johhny come lately when it comes to rhythm, but I digress.)
 
Thanks Dave !

I was thinking something along that line as well; that the video suggests, optimistically perhaps, that if a band plays together long enough, eventually they'll all fall into the same groove.

yes perhaps,
praayin' for grooves and not ruts ; )

(who has vowed not to play anymore shows with prementioned guitarist who resonates with the blue metronome )
