Piano hand position and posture

How to sit at the piano

Start with the seat, because everything above it depends on it. Sit down and set yourself up in this order:

Height. With your hands resting on the keys, your forearms should be about level with the keyboard, or sloping slightly down towards it. If your wrists have to bend upwards to reach, you’re too low; if your shoulders lift or your elbows fall well below the keys, adjust the other way. An adjustable bench makes this easy. On a fixed chair, a firm cushion or a folded blanket raises you.
Distance. Sit far enough back that your elbows are slightly in front of your body, not tucked behind it. A quick test: you should be able to reach the lowest and highest notes by leaning, without sliding along the bench. Too close and your elbows jam against your sides; too far and you reach with your shoulders.
Where on the bench. Sit on the front half, so your weight is on your sitting bones and your thighs are free. Sitting right back on the seat tends to make you slump.
Feet. Both feet flat on the floor, the right one near the sustain pedal so it can reach it without moving your body. Children and shorter adults whose feet don’t reach can use a footstool or a sturdy box.
Centre and back. Sit roughly opposite middle C, upright but not stiff, leaning very slightly forward from the hips. Your back does the holding up; your arms should feel as if they have nothing to carry but themselves.

The correct piano hand position

You don’t need to invent a hand shape. You already have a good one. Stand or sit, let your arm hang loosely by your side for a few seconds, and look at your hand: the fingers curve gently, the thumb rests a little away from them. Now lift the arm and place that hand on the keys without changing it. That’s the shape.

You may have been told to hold an imaginary ball or an orange. The idea is right, but many people take it too far and claw. The hanging hand is a better guide, because it’s already relaxed.

Fingertips. Play on the pads near the tips of the fingers, not on the flat of the finger. Short nails help more than anything else here.
The thumb on its side. The thumb plays on its outer edge, near the corner of the nail, lying fairly flat along the key rather than pointing down into it.
Firm joints. The joint nearest each fingertip stays firm as the key goes down, so the finger doesn’t buckle backwards. The big knuckles where the fingers join the hand make a gentle arch, not a dip.
A level wrist. The wrist sits roughly in line with the back of the hand: not dropped below the keys, not raised in a hump. Level doesn’t mean locked. It rises, falls and turns a little as you play, and that small movement is what keeps it free.

Use the weight of your arm, not finger squeezing

A piano key needs surprisingly little force to go down. What makes a full, round sound is weight, not effort: the relaxed weight of your arm passing through a firm fingertip into the key. Squeezing from the fingers and forearm makes a harder sound and tires you quickly.

Try this. Rest your third finger on a key. Let your arm go loose, as if it were hanging from the shoulder, and let its weight sink through the fingertip until the key reaches the bottom. Notice that once the key is down you don’t need to keep pushing: just enough to hold it there. Then let the arm float up and the key rise with it. Do it with each finger in turn, a few times each. That feeling of weight in, then release, is the basis of good tone, and it’s also what legato playing is built on.

Relaxed shoulders and free elbows

Shoulders creep up when you concentrate, especially when reading something new. Keep them low and wide. Your elbows should hang freely, neither pinned to your sides nor winging out. As your hands travel up and down the keyboard, the upper arm and elbow move to carry the hand there, so the fingers arrive in the same comfortable shape instead of stretching sideways from a fixed elbow.

Keep breathing, too. Holding your breath through a hard bar is common, and it tightens everything else.

A tension check every few minutes

Tension builds without your noticing, so check for it on purpose. Every few minutes, or at the end of each piece or exercise, stop and run through this:

Shoulders. Have they risen? Lift them on purpose, then let them drop.
Jaw and breath. Unclench, breathe out slowly.
Elbows. Are they hanging freely, or held against your body?
Wrists. Make a small, gentle circle with each one. If it won’t move easily, it was held stiff.
Thumbs. Is either one pressing on its key when it isn’t playing?
Resting fingers. Fingers that aren’t playing should rest lightly on or just above their keys, not lift stiffly into the air.

It takes about ten seconds. After a few weeks you start to notice tension as it begins, and the check becomes a habit rather than a list.

Keyboards on stands and tables

Many people learn on a digital keyboard, and this is where set-ups most often go wrong. A keyboard on a kitchen table is usually too high for a dining chair, and a desk chair with arms and wheels pushes you too far back and rolls away when you lean.

Match the height to the seat. If your stand adjusts, sit on your seat first, then set the stand so your forearms are level with the keys. If it doesn’t, adjust the seat.
Use a proper bench or a firm stool without arms or wheels, so you can sit forward and lean freely.
Keep it steady. A keyboard that wobbles makes you play cautiously. Tighten the stand, and put the pedal where your right foot falls naturally, on a mat or against something so it doesn’t slide.

Common faults and how to fix them

Fault	What you’ll see	Fix
Flat fingers	Playing on the whole length of the finger; notes sound uneven.	Let the arm hang and copy its curve. Move the hand slightly forward on the keys so the fingertips land on them.
Collapsed first joint	The tip joint bends backwards as the key goes down.	Play slowly with light weight on one finger at a time, watching that joint stay firm. Add weight only as it holds.
Raised wrist	A hump above the hand; often with the seat too low.	Check the seat height first. Then let the wrist sink until it’s level with the back of the hand.
Little finger flying up	The 5th finger sticks up stiffly while others play.	Rest it on its key while the others play. Play slow patterns that use it often, such as C D E F G and back.
Thumb hanging off the keyboard	The thumb droops below the keys, pulling the hand out of shape.	Keep the thumb resting on the white keys, on its side, ready to play, even when it has nothing to do.

Fix one at a time. Pick the fault you notice most, give it your attention for a week of easy pieces and simple finger exercises, then move on to the next. Easy music matters here: when the notes are hard to read, attention goes to the page and the hand falls back into old habits. Pianomi’s wait mode helps for the same reason, because the music waits for each note and there’s no beat to rush you.

If something hurts, stop

Playing the piano shouldn’t hurt. Muscle tiredness after a long session can be normal, but pain, tingling, numbness, or an ache that lasts after you’ve stopped are signs to stop practising and get your set-up checked by a teacher. If it carries on, see a doctor or a physiotherapist. Shorter sessions with breaks are kinder on hands than one long one, especially when you’re starting out or learning something new.

With the posture in place, the next things to learn are how your fingers are numbered (see piano finger numbers) and, later, how to keep this ease as you play faster.
