Most drummers hit the same wall: they read 80 BPM on the page and play 80 BPM from day one, then wonder why their 16th notes get mushy and their wrists tighten up.
The disciplined path is 60 BPM first — strict four-stroke singles, doubles, paradiddles, flams, diddles — every interval of every stroke perfectly even, both hands at identical dynamic. You do not have that kind of bandwidth above 60. Once you are clean there, 70, then 75. Patience is the whole game.
This page sets 60 BPM, 4/4, traditional drum. The first strike of every bar is the accent (your hand or your hi-hat foot), the next three lighter. Hit the button and start. One week at 60, then add five every week. In two months you will be shocked at how much slow time actually adds up.
The app pre-sets to 60 BPM, 4/4, traditional mode. To adjust, use the controls inside the app after it loads.
