Each level is one continuous chart. Tap every note in time — perfect within ±45 ms.
Rhythm is the one part of music where being nearly right is audible. These drills score how far each tap lands from where it should, in milliseconds, so the gap between knowing a rhythm and placing it stops being a matter of opinion.
There is a difference between reading a rhythm and playing it. You can look at a bar of sixteenths, understand exactly what it means, count it correctly out loud, and still tap it late — because placing a note in time is a motor skill, and understanding is not.
That is why these levels measure timing rather than pattern-matching. Each tap is compared against where the note actually falls and scored on the distance, so a run tells you not just whether you played the right rhythm but whether you were consistently ahead of the beat, consistently behind it, or unstable in both directions. Those three failures need different fixes, and they are indistinguishable by ear when you are the one playing.
The material moves through quarter-note control with rests and pickups, then offbeat and anticipated figures, then sixteenth grids with roaming accents, then the rudiments — singles, doubles, and the single paradiddle — where each note carries a marked hand and sticking becomes part of what is being tested.
Count the subdivision out loud, not the beat. Counting 1, 2, 3, 4 tells you where the beats are and nothing about what happens between them; counting 1e&a 2e&a puts a name on every position a note could occupy, which is what makes a syncopation land rather than approximately land.
Take the tempo down further than feels necessary. Timing errors shrink in absolute terms as tempo drops, so a slow pass is where you can actually hear a twenty-millisecond rush. If a pattern is clean at a slow tempo and messy at a fast one, the problem is tension rather than comprehension, and playing it fast repeatedly will not fix it.
Rests deserve as much attention as notes. Most rhythmic instability shows up on the beat after a rest, because a silent beat is one you have to keep counting through with nothing to confirm you got it right. Stay poised through the gap rather than relaxing and restarting.
