Analyze music (discovering their key, the #harmonicprogression or alterations in key), #improvising on them or compose new has never been easier!
Musically, the crux of the wheel is represented by the well-known #circleoffifths (C, G, D, etc.)
Added to this is a smaller inner circle that represents the sequence of minor #chords built on the vi degree (considering the notes of the circle of fifths as tonic and present immediately above). It is precisely on the VI degree that you build the natural minor or relative minor scale. For this reason we can also consider this inner circle as the succession of the "relative minors". Therefore, under C we will have the A- chord while under G we'll have the E- chord etc.
The outer points (the ones that symbolize the sun's rays) represent the VII degree, considering the note right below as the tonic of the scale of reference.
Isolating three rays from the wheel will get a figure very similar to a diamond. Each diamond contains a myriad of information.
The Roman numerals denote the harmonic progression of chords created on the scale. The upper case ones (I, IV, V) represent major chords while the lower case ones (ii, iii, vi) are minor chords. The degree with the small circle instead represents the VII degree on which, in the major scale harmonization, a half-diminished chord is built.
The abbreviations in bold represent both the name of the specific chords and the notes which make up the major scale of reference.
Within the diamond's perimeter we'll therefore also have the name of all the notes that make up the C major scale. In our case: C, D, E, F, G, A, B, or if we consider the degrees I, ii, iii, IV, V, vi, VII.
This instrument will also be useful for composing songs and improvising. In fact, if I'm writing a song in C, I can already identify the chords to develop my harmony on, and thus also easily find more interesting solutions for my melody.
