A teaching device for stringed musical instruments used by a player thereof to identify, practice and make changes between notes of scales of different keys. It is constructed of a simulated fingerboard comprising a rigid support surface (56) with magnetic guide members (51-54) therein and a set of structurally like note index units (as 101- 128) each of such units comprising an upper label bearing panel (81) and a lower support and attaching magnetic element (83) and each of such units being removably yet stably locatable on the fingerboard. The apparatus components are organized to correspond with written music notation and operate to provide (a) a visual and tactile guide for proper finger positioning on the fingerboard, (b) finger positioning practice and (c) visual signal when finger positions are improper, and (d) facilitate removing, displacing and positioning of such units to indicate proper finger positioning for operating in different keys. |
