As a whole, the book is a compact resource designed to guide the beginning of your musical journey and add some colour to the following:

⁍ The tuning system known as 12-TET (12-tone equal temperament) divides the tonal range into octaves, each subdivided into 12 equal logarithmic steps — giving rise to 12 tones.
⁍ The 12 tones are labelled as follows: 7 natural (A, B, C, D, E, F, G) and 5 sharp/flat (A♯/B♭, C♯/D♭, D♯/E♭, F♯/G♭, G♯/A♭).
⁍ Across the range, each set of tones gives rise to a corresponding tonal domain — within which scales can be built using any scale pattern.
⁍ A given scale pattern can be transposed to all tonal domains — creating a particular tonal system of 12 musical milieus specific to that scale pattern.
⁍ Rotations of the given scale pattern produce a certain number of scales — all related and belonging to the same milieu, each identifiable by a tonal centre and a certain tonality (general sound).
⁍ Rotations of the scale pattern formed by the 7 natural tones (A–B–C–D–E–F–G) creates a fundamental tonal system, here referred to as The Diatonic tonal system. The seven scale rotations are labelled Aeolian, Locrian, Ionian, Dorian, Phrygian, Lydian, and Mixolydian — named after ancient Greek regions of Asia Minor.
⁍ For indexation purposes, these labels are mapped to the ROYGBIV color sequence — R (red) for Aeolian, O (orange) for Locrian, Y (yellow) for Ionian, G (green) for Dorian, B (blue) for Phrygian, I (indigo) for Lydian, and V (violet) for Mixolydian.
