Yes. This is how I've started practicing 8th notes on the hi-hat for quicker tempo's. Using the butt of the stick makes it stick out more than the push-pull. But I've seen guys using it palm down and flicking wrist and playing really fast.I didn’t think there was a difference in sound between conventional playing and side-sweeping, but the difference is significant on the hi-hat. It took me a while to get used to it, and playing that way (side to side while also striking downward enough to make the desired sound and tempo) is difficult for me over a long period. I play hi-hat right-handed and have found it works best for me to point the palm-side of my wrist toward my left shoulder. This way the movement is still an up and down movement, with a little side-movement thrown in.
Do others do it the same way?
