Proper Thumb Technique for Piano Playing
Understanding how to use your thumb correctly is key to developing good piano technique. The thumb works differently from the other fingers, so it needs special attention to move smoothly and without tension.
Common Thumb Issue No. 1: Wrong Contact Point

One issue is when the thumb hits the key too low, below the nail line. This pulls the wrist down, messing up your hand’s position and causing tension, which makes playing harder. To fix this, make sure your thumb touches the key on the side of the nail. This keeps your wrist and hand aligned, making it easier to play with control.
Common Thumb Issue No. 2: Not Resting on the White Keys

Beginners sometimes do not keep their thumb resting on the white keys when it is not in use. This can cause the thumb to be out of position, leading to inefficient movement and unnecessary tension. The thumb should rest lightly on the white keys, ready to play, to maintain proper hand alignment and readiness.
This often happens because beginners play too close to the edge of the keys, and the thumb has trouble finding a place to rest. By moving your fingers closer to the center of the keys, your thumb will naturally find a good resting spot.
