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 logarithmically-equal 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 of the 12 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 (overall 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.
