Why Practising Piano Slowly Works (and How to Do It)

If you take one practice habit from this article, make it this: slow down. Almost every music teacher gives the same advice, and for good reason.

Why slow practice helps

When you play a passage faster than you can control, mistakes become part of the habit. Playing slowly gives your eyes, ears and fingers time to agree on what the next note is. It lets you notice a wrong finger or note before it sets in, and it helps you play each note the same way every time. Speed is the result of accuracy, not the other way around.

Choose a starting speed

A good starting speed is one where you can play the whole passage without stopping or guessing. For a new song that is often about half of the final speed. In Hey Piano 4U you can start at 40% or 60% with the Speed dial.

Use the song’s pace-setting modes

Watch the song once so you know how it should sound.
Use Follow mode. The song waits for you at every step. Your only job is to press the right key.
When Follow feels easy, change to Play along at a low speed, where timing counts.
Raise the speed a little at a time, for example from 60% to 70% to 85% to 100%.

Loop the hard bars

Most songs have one or two tricky spots. After a run, Hey Piano 4U lists the bars where you slipped most. Tap one and it loops two bars at a slower tempo so you can drill just that part. Playing a short section ten times is more useful than playing the whole song ten times.

Let the tempo adapt

The Auto speed option raises the speed by 10 percentage points when you play a run at 90% accuracy or better, and lowers it when accuracy drops below 60%. It is a simple guide to keep you in the zone where practice is challenging but not frustrating.

Other slow-practice habits

Practise hands separately, then together.
Use a steady pulse. Tap your foot or count aloud.
Stop on a success. End each session by playing something you can do well.
Take breaks and keep your shoulders, wrists and fingers relaxed.

Speed will come on its own. Try a song at 60%
