Jazz Scale - Modes of The Melodic Minor Scale

Modes of The Melodic Minor Scale

A great deal of modern jazz harmony arises from the modes of the ascending form of the melodic minor scale, also known as the jazz melodic minor scale. (see jazz minor scale) This scale is essentially a diatonic major scale with a flatted third, for example C D E♭ F G A B C (Exactly the same as in "classical" music and its theory, in Jazz the melodic minor scale's sixth and seventh are not necessarily flattened when descending). As with any other scale, the modes are derived from playing the scale from different root notes, causing a series of jazz scales to emerge.

Modes of C ascending melodic minor:

i ascending melodic minor T, 2,♭3, 4, 5, 6, 7 (associated with C- maj7 or C-6 chords, functions as a i minor)
II Phrygian ♮6 (or Dorian ♭2) T,♭2,♭3, 4, 5, 6,♭7 (associated with D7 sus ♭9 chord, functions as a dominant)
III Lydian augmented (Lydian ♯5) T, 2, 3,♯4,♯5, 6, 7 (associated with E♭ maj7 +5 chord, functions as a I+)
IV Lydian dominant (also, "Lydian ♭7")(also known as Mixolydian ♯4) T, 2, 3,♯4, 5, 6,♭7 (associated with F7 ♯11 chord, functions as a dominant not going to I)
V Mixolydian ♭6 (or simply "fifth mode") T, 2, 3, 4, 5,♭6,♭7 (associated with G7 ♭13 chord, functions as a dominant)
vi Locrian ♮2 (also known as "half-diminished" scale) T, 2,♭3, 4, ♭5,♭6,♭7 (associated with Ami7 ♭5, which functions as a ii chord in minor)
VII Super Locrian (also "altered dominant scale", or "altered scale") T,♭2,♭3, ♭4,♭5,♭6,♭7 (associated with B7 ♯9 ♭13 chord, functions as a dominant)

It should be noted that the names of these scales are variations of the names used for some of the modes of the diatonic major scale, for example the Phrygian Natural 6, the second mode of the melodic minor, is named so because it is the same as the Phrygian mode of the major scale except with a raised (i.e.,♮6) sixth.

    A child who fears excessive retaliation for even minor offenses will learn very early on that to lie is to protect himself.... If your child intuits that you will react very punitively to his wrongdoing, he may be tempted to lie and may become, as time goes on, a habitual liar.
