Posture at the piano influences how the piano is played and how it sounds. The comfort and well being of the pianist is also at stake. Correct seating position will foster the natural development of correct technique and musical playing. It is of vital importance that correct posture is used from the very beginning, whether sitting at a keyboard or a piano.
When sitting at the piano, the pianist should sit on the front half of the bench. The bench should be moved out far enough that the knees only come under the edge of the keyboard by a couple of centimetres. The knees should be comfortably apart, providing support for the body when leaning or shuflfing left and right, reaching across the keyboard. The feet should be slightly forward of the knees and flat on the floor or on a stool if the floor cannot be reached. When sitting up straight, but not stiffly, it should be possible to lift the hands in a relaxed, cupped position and place them on the keys parallel to the floor. The elbows should be slightly out and forward from the sides of the body, but in a relaxed way, not a lifted position. If the forearms are not parallel to the floor and slightly higher than the keys, it is necessary to add a cushion.
Often, a child will need adjustments made to enable correct seating. Parents need to check posture and make any necessary alterations (e.g. adding cushions and footstools), teaching a child to always check seating position before playing the piano.
