Practice method
Practise slow, earn your speed
Updated 3 August 2026 · 4 min read
Repetition writes down what you did, not what you meant. Ten passes at 140 BPM with a tight grip and a late kick teach the tight grip and the late kick, ten times, at speed.
Speed is what accuracy becomes once enough clean repetitions have gone in. The work is finding the tempo where they do, and moving up on evidence instead of ambition.
Does this sound like you?
- You play a pattern fast and messy or slow and clean, with nothing in between.
- Your weak hand quietly disappears above a certain tempo.
- Fills accelerate, and the bar after the fill arrives early.
- Your forearms burn after two minutes and the groove gets worse.
If two or three of those sound familiar, you are in the right place. Here is what is behind it, and what to do about it.
What is actually going on
Above your clean tempo the technique changes shape rather than simply degrading. Strokes shorten, the grip tightens, the weak hand starts pushing from the arm instead of letting the stick rebound, and that tension feeds straight into rushing. The ceiling and the sore forearms are one problem, and opening the grip moves both.
The slow tempo is also the only one where you can hear detail. At 76 BPM a ghost note is audibly a ghost note: a dull tap under the hats with no ring on it. At 140 it is a smudge, and nothing gets fixed while it goes past too fast to perceive.
Which is why the ladder below moves in 4 BPM steps. Ten is a jump you can bluff your way through; four is small enough that when it breaks, you know what broke.
The drill: The clean-tempo ladder
- Find your clean tempo. Drop the click until you can play the pattern five times through with nothing you would apologise for — usually 20–30 BPM below where you have been practising.
- Play it there for two unbroken minutes, counting out loud. Boring is correct: the gain is in the repetitions after it stops being interesting.
- Raise the click by 4 BPM. Not ten. Play the same two minutes.
- One flaw you can hear and you go back down two steps and rebuild. Pushing through is the entire mistake.
- Finish the session at your clean tempo, not your fastest. The last thing you play is the version you rehearsed last.
Target. Two unbroken minutes 8–12 BPM above last week’s clean tempo, with the accuracy you had at the slower one and no drift as the take goes on.
How iQuantize measures it
You decide for yourself whether a tempo was clean, which is the weak point in the method. At your working edge the errors are 15 to 20 ms — too small to hear while your attention is on playing.
iQuantize supplies the number instead: every hit marked green, orange or red on the engraved chart as the playhead passes it. The scores that decide whether the step was earned do not move at the same rate:
- Timing stability falls first — the spread of your hits around your own average. Hold the same 15 ms lateness and widen the scatter from 5 ms to 20 ms, and it drops from 97 to 89.
- Timing with the click hardly registers that: 99 to 97 over the same change. Anything inside the ±80 ms green window takes full credit on the window term, so sitting 15 ms behind consistently costs almost nothing — the app names the offset at ±8 ms rather than deducting for it.
- Note accuracy catches the notes that quietly stopped arriving, usually weak-hand ghosts and the second kick.
- Dynamic control goes next, because a rushed stroke has no room left for a soft one.
So the rule is: move up when stability holds, not when the take felt fine. Two takes at one tempo on different days is evidence; one good take is luck. Nothing in the app pays you for the bigger number either — no points economy, no ladder to climb by turning the click up.

Common questions
How slow is slow enough?
Slow enough to hold a conversation while you play. If that feels insultingly easy it is probably right: the errors you are removing are 15 to 20 ms wide, and you will not hear them at a tempo that takes all of your attention.
How quickly can I raise the tempo?
Four BPM a step, and no more than one successful step a session. Unglamorous, and still faster than attacking a single tempo for a year, which is how most plateaus get built.
Does this apply to grooves as well as rudiments?
More so. A rudiment breaks down obviously. A groove breaks down invisibly, the kick sliding late while the hands still sound fine — a limb independence problem wearing a speed costume.
