Abstract
Abstract A device for studying music concepts, in which, a teaching sheet having a musical staff entered therein is set under a transparent plate having transparent conductive films disposed corresponding to the lines and inter-line spaces of said staff of said teaching sheet, and by teaching a specific scale note of the staff with a conductive contact bar, a corresponding sound may be produced. Thus music pupils learn through their eyes and ears by means of this device. By using this device in combination with an overhead projector, group studies may be made effectively in a school room. Further, the teaching sheet and transparent plate may have certain patterns of musical instruments for studying playing positions.
