ABSTRACT

In modal jazz theory, diatonic modes are traditionally introduced as derivatives of the parent major scale. What might be a bit confusing in this method is that the parent scale is also a mode, named Ionian. The parent-scale method is based on constructing modes on the consecutive pitches of the major scale. In Figure 7.1, Dorian begins on 2^ of the C major scale and represents an ordered diatonic collection stretching from D4 to D5 (or any other octave); Phrygian starts on 3^ and covers an octave from E4 to E5; Lydian begins on 4^ and spans an octave from F4 to F5; Mixolydian starts on 5^ and extends from G4 to G5; Aeolian begins on 6^ and covers the distance from A4 to A5; and Locrian starts on 7^ and includes pitches between B4 and B5. Figure 7.1 shows the derivation of modes using the parent-scale methodology.
