What significance are the COLORS
on The Music Wheel?
Notice that the color coordinates are opposite (or across the wheel) from one another. For example, view the green slice that lists A major and its minor relative f #. Opposite (across the wheel) is a green slice that lists A flat major and f minor. The Keys opposite or across The Music Wheel are half-step tones from one another.
The orange slice containing E major and c#minor are opposite (or across) from E flat major and C minor, also an orange slice. These opposite Keys are half-step tones from one another.
The lavender slice containing B major and g# minor are across from B flat major and g minor, also a lavender slice.These opposite KEYS are half-step tones from one another on a keyboard or on a fret board.
Notice that there are two color slices that are red separated by a blue slice. These two slices are C major and a minor, and D major and b minor. These two red slices are across from two adjoined color red slices called enharmonics--Keys notated differently on the staff, but voiced identically .These are also half-step tones from their color coordinates.
In addition, there are two color slices that are blue separated by a red slice. These two slices are F major and d minor, and G major and e minor. These two blue slices are opposite or across the “...Wheel™” from adjoined color blue slices called enharmonics—Keys notated differently on the staff, but voiced identically. These are also half-step tones from their color coordinates.
