Manually Operated Educational Device and Method for Conveying Relative Music Theory Concepts for Multiple Instruments

摘要

An educational device permitting the conveyance of multiple relative topical concepts and method for applying music theory to multiple instruments. The described embodiments have a front layer and back layer, with a plurality of windows permitting visibility of two rotationally mounted inner discs having central pivotal attachments that secure all physical elements. The first and second embodiments illustrate music theory concepts pertaining to chords on the front layer, and music theory concepts pertaining to scales on the back layer. Information imprinted on each side of the inner discs is organized in the musical cycle of fifths to align with the windows on the outside layers and is relative imprinted information of the outside layers. The inner discs are synchronized for the consistent display of selective information, permitting a user to determine the physical application of chords and scales in any key and harmonic relationships. Other embodiments are described and shown.
