seeing as the backbeat is most usually the anchor for nearly all popular music. when i play listening to the metronome as on beats and playing 16th notes, above 150 or so, it's like i'm pushing to get through the notes, with a lot of tension and my accuracy suffers. but then if i perceive it as 8th notes at 300bpm with the clicks as 2 and 4...i have no tension and i'm more accurate. there are a lot of jazz teachers out there that are like "use the metronome as 2 and 4." so is the straight way really necessary? what gives, why is it easier to me the second way? should i just use it this way if it's working well for me for increasing speed and accuracy and then go back and clean up later?
