Why Practise Slowly?

Not a slow performance — a rewrite of the action with the brain present

"Practise slowly" — almost every player has heard it. Few are told why, so it degrades into a slogan: slow practice as detention, fast playing as the real skill.

The mechanism is the opposite: at speed, the brain cannot supervise the action. Eyes, ears and fingers are all rushing; errors get buried by velocity and legalised by repetition — and by the time it feels "learned", what is learned is the wrong version. Fixing it later, at speed, is harder than learning it fresh.

Slow gives three things back

Slowing down returns three words to the brain:

• time to think: before each move you *know* what comes next — instead of fingers first, brain chasing;
• attention to listen: spare capacity to check tone, intonation, buzz;
• room to correct: a mistake can be stopped the moment it happens, not carried to the end of the phrase.

How slow is slow

Not "a bit slower than normal" — slow enough for three standards:

1. Fully relaxed — no clenched shoulder, wrist or jaw; 2. Ahead of the hands — while playing this note, the next is already prepared; 3. Sayable — you can state what this pass did and where it was right.

Miss any one and drop the tempo another notch.

The rule for speeding up

Slow practice is not the goal; it is production capacity:

• Three clean passes in a row → +5 to +10 BPM (the next click on the metronome);
• One mistake → step back one tempo — not "one more try should fix it".

Remember: speed is added, not charged at. A "fast" gained by force is usually repaid in retraining.

Two common misreadings

• "Slow practice just means playing slowly": no — it means doing every detail right at a slow tempo. Slow without focus practices nothing;
• "Slow practice is boring": keep it to fifteen minutes a day and play the fun stuff after — slow work and enjoyment coexist, as long as one does not pretend to be the other.

Listen: 60 BPM, the default

Let every beat land exactly where it belongs. This is slow practice's metronome setting: the speed at which you can be correct — not the speed at which you sound like the record.
