Summary of the invention

The purpose of the utility model is the difficult grasp property to mode in the present music field and harmony study, proposes a kind of convenient practical tool that can intuitively show between each mode of music such as variation relations such as the system of Himdu logic, roll call, interval, sound number, modulation and chords.

A kind of tonality and audio disc is characterized in that, comprise the shrouding disc at shallow bid, mid-game, deep bid and the deep bid back side, and the diameter of said shallow bid, mid-game and deep bid increases progressively successively, and the diameter of said shrouding disc is identical with deep bid; The shrouding disc at said shallow bid, mid-game, deep bid and the deep bid back side is that axle is movably connected with the core, can relatively rotate around axle between each dish; Have seven groups of scallop holes on the said shrouding disc, be circle-shaped average five equilibrium on the card of said shrouding disc.

Tonality and audio disc that the utility model proposes, wherein, the shrouding disc at said shallow bid, mid-game, deep bid and the deep bid back side is to be riveted together at the core place through rivet.

Tonality and audio disc that the utility model proposes, wherein, the diameter of said deep bid and disk cover is 125mm, and the diameter of said mid-game is 80mm, and the diameter of said shallow bid is 54mm.

The beneficial effect of the utility model is that the design of tonality and audio disc can be in harmony teaching and writing, as aid; Can embody the functional character of chord more intuitively, show the color character of big ditty, the relation between the mode, can let each common chords commonly used of transferring in clear and definite 24 the big ditties of user more easily; The musical alphabet of seventh chord; Clear and definite respectively nearly related key of accent, and common chord provide the simple and easy apparatus that people learnt, used harmony theory and skill and technique.
