So if I turn my metronome on and have my feet tapping 8th notes w/ right foot doing the first half of beat and left foot doing the 2nd half of the beat, and then displace my sets of 5 so that they are starting on the 2nd half of the beat (ie when my left foot hits the floor) there are two things that I am uncertain off. First of all, I am not 100% sure that I am continuing to do them 100% evenly. And Secondly, I am wondering how my sets of five should correspond to the right foot comming down. (ie when my metronome is telling me that I need to move on to the next beat) Should it be on 3 or half-way between the 3 and the 4?

If you're counting 8th notes:

1 & 2 & 3 & 4 &

40 notes

12345 &2345 22345 &2345 32345 &2345 42345 &2345.

That can get a little busy at higher tempos. Suggest you use Quarter notes.
Start slow and lock in like a machine.

1 2 3 4

12345 22345 32345 42345

FUFU2 FUFU2 FUFU2 FUFU2 :-)

Once you get Quarters then you can move to 8th's, triplets ,16th's and go Virgil Donati crazy!!

Gradually increase tempo as you gain more command! Good luck!
