<p>A playing aid is disclosed to be mounted on the hand for positioning the thumb and fingers to enable the playing of selected intervals of musical pitches on a keyboard instrument such as a piano, organ, synthesizer and the like. The thumb and fourth finger are rigidly held apart a predetermined amount by a pair of grips (12, 13) interconnected by a raised bridging portion (11) adapted to elevate the remaining fingers above the plane of the grips. The device enables simultaneous depression of at least a pair of keys corresponding to selected tonal intervals.</p> |
