The present invention relates to a music chords conversion device. The device is used for providing instant representation showing conversion or correlation of major chords to minor chords and vice versa. The device can come in two variants (1) a physical device (2) a digital device. The physical device has a chords conversion component and a minor chords component wherein the minor chords component is configured to slide into the chords conversion component through a cut-out opening. The minor chords can be correlated to the major chords and displayed in a viewing region of the chords conversion component. The digital device includes a memory for storing the chords conversion and also includes a digital display for displaying the converted minor and major chords.

The invention provides a device for music theory comprehension. The device includes a base portion and a first stencil. The base portion includes a plurality of marks. Each mark includes indicia representing a musical note. The first stencil includes a first interior shape, wherein the first stencil and the base portion are selectively positionable relative to each other. At each of a plurality of predetermined positions determined by the plurality of marks, the first interior shape of the first stencil surrounds multiple marks. The multiple marks include indicia representing seven musical notes representing a unique chord family.
