Abstract: A universal upper back support primarily for piano and organ benches has been created, and is easily attached to any wooden bench used for instrument playing. The back support contains a cushion which is positioned at the correct angle by two vertical side pieces for engagement with the musician's upper back, and allows free movement of the arms, hips, and legs in any direction without any hindrances while the musician plays a selected instrument. The vertical side pieces may each optionally have a lower front indentation to allow easy opening of the hinged top seat of a music bench having an interior storage space, and the back support can be alternatively made with a manual adjustment mechanism that allows finger-activated vertical height adjustment of its cushion in selected pre-drilled holes. The back support can be provided with an installation template for ease of user installation.
