The device uses tones that, together, make up a synthetic hexatonic scale (0 1 4 6 7 t). When enharmonically spelled C–D ♭ –E–G ♭ –G(♮)–B ♭, it is called the tritone scale.

A scale of chords may be used to set or read an angle in the absence of a protractor. To draw an angle, compasses describe an arc from origin with a radius taken from the 60 mark. The required angle is copied from the scale by the compasses, and an arc of this radius drawn from the sixty mark so it intersects the first arc.
In contrast, in the chord-scale system, a different scale is used for each chord in the progression (for example mixolydian scales on A, E, and D for chords A 7, E 7, and D 7, respectively). [5] Improvisation approaches may be mixed, such as using "the blues approach" for a section of a progression and using the chord-scale system for the rest. [6]
The augmented scale, also known in jazz theory as the symmetrical augmented scale, [3] is so called because it can be thought of as an interlocking combination of two augmented triads an augmented second or minor third apart: C E G ♯ and E ♭ G B. It may also be called the "minor-third half-step scale", owing to the series of intervals ...
The Grandmother chord is an eleven-interval, twelve-note, invertible chord with all of the properties of the Mother chord. Additionally, the intervals are so arranged that they alternate odd and even intervals (counted by semitones) and that the odd intervals successively decrease by one whole-tone while the even intervals successively increase by one whole-tone. [13]
Minor chords are noted with a dash after the number or a lowercase m; in the key of D, 1 is D major, and 4- or 4m would be G minor. Often in the NNS, songs in minor keys will be written in the 6- of the relative major key. So if the song was in G minor, the key would be listed as B ♭ major, and G minor chords would appear as 6-.
The Ionian mode is a musical mode or, in modern usage, a diatonic scale also called the major scale.It is named after the Ionian Greeks.. It is the name assigned by Heinrich Glarean in 1547 to his new authentic mode on C (mode 11 in his numbering scheme), which uses the diatonic octave species from C to the C an octave higher, divided at G (as its dominant, reciting tone/reciting note or tenor ...
