I have no problem chopping on the off beat at reasonable speed, 90, 95, 100, 105 BPM in 2/2. I can either just hit on "and" or do a muting tick on "one" and "two" and then chop on the "ands".
When I gets pretty fast, somewhere above 115 or 120, I find it real tough not to lose it, or a least feel like I'm losing. Like at 105, I can just sit in the groove like a rocking chair but it gets blurry when it's real fast. Maybe I'm still on but it's real hard to hear if I am.
Sometimes I tick on the down beat and chop on the off beat, effectively playing "1 and 2 and" 1/8 notes with downstokes accenting chops on the "ands". Sometiems I just hit the "ands" only.
Yestersday, while listening to some fast BG in the car, I tapped my left foot to the beat 1/2/1/2 and trying tapping my shifter on the thumb. I go do the "1 and 2 and" but I kept accenting the 1 and 2 and not the "ands".
I guess part of it is doing anything clean at a speed is praticing slowing, working up and going back down to. Not sure whether I should practice with the extra ticks or not, or maybe do both?
I also kinda wonder about "ceiling of addaptability". Could my reaction be hard-wired so that I'll never be able to play at a certain speed no matter how carefully I practice.
So, anyone got tips?
