Your elbows should be at a comfortable distance from your body, bent outward. As you move up and down the keyboard with your fingers, your elbows should move along in a smooth, fluid motion. As your hands move apart and reach for the ends of the keyboard, your arms open up to a comfortable playing position.
What is the correct hand position for piano?
A good hand position is when both hands are palms down, relaxed and resting slightly above the keyboard. The wrists should be relaxed and straight. The fingers should be slightly extended but also relaxed. The power it takes to press down the piano keys comes from the hand itself, not the individual fingers.
Where should you sit when playing piano?
The correct height
When sitting at the piano you want your elbow and arm to fall freely from your shoulder. Your forearm should be parallel to the floor, and your arm should be at an angle slightly more than a right angle. Adjust your seat to get the right height.
