ErgoPlay Professional Guitar Support for lefthanded kids. This support is the most stable, adjustable, and ergonomic of all guitar supports. It helps put the guitar in its optimal playing position and can eliminate back problems caused by poor positioning. Since the fifteenth century or earlier guitarists have raised their left leg up by stepping on a guitar case or foot stool, to improve their technique. By doing this their arms and hands work in a superior way but at the same time it creates a curve in the back which manifests long term problems such as back aches. The guitar feels more comfortable with the Ergoplay than in the traditional Segovia position. Not only that but the position of both hands makes playing easier and more efficient than before.
