Polyrhythms. Odd meters.
Surgical precision.
All 9 drills, the full pattern editor, and AI that does the math on a 5:3. For drummers who've outgrown apps that stop at 4/4 and a backbeat.
Advanced practice tools
Polyrhythm drill
Stack two rhythms and internalize the relationship. 8 preset ratios in both polarities — flip 3:2 to 2:3, work up to 5:4 and 5:3.
Odd time signatures
Build patterns in 3/4 through 7/8, mixed meters included. The Time Signature Builder drill takes the click to 15/8 — group a 7 as 2+2+3 or 3+2+2 and the accents follow.
Click displacement
Shift the click to any subdivision. Forces you to own the pulse internally, not just follow the click.
Internal clock
The metronome drops out for bars at a time. When it comes back, you find out if you drifted.
Full pattern editor
Place every hit on every voice. Build complex polymetric patterns, linear grooves, and progressive exercises.
AI for complexity
Describe complex patterns in English. The AI handles the math of polyrhythmic placement and odd-meter subdivisions.
A polyrhythm ladder that sticks
Most drummers learn 3:2 as a party trick and stall there. This is the four-rung version that turns ratios into feel.
3:2 at 60 BPM
Hands play 3, foot keeps 2. Count the composite out loud — "1, and-a, 2, and" — until the two lines stop being math and start being one rhythm.
Internalize it
Drop the counting. Move the 3 around the kit — hat, ride, floor tom — while the 2 stays planted. When you can hold a conversation over it, it's yours.
Step up to 4:3
Same process, denser math. The drill plays both sides of the ratio so you hear the target before your hands attempt it.
Displace the click
Move the click off the downbeat and hold the polyrhythm against it. This is the graduation exam — where the ratio becomes time, not arithmetic.
