Relation with Major Scale: It is a variation of the major scale in which the fifth is lowered by a semitone.
Theoretical Aspects
Sound Character: A scale that maintains the typical brightness of the Ionian, but the diminished fifth creates a fracture that gives a surreal color and internal tension.
Typical Chord: Maj7♭5
Modal Context: Works well on static modal passages or in contexts where one wants to destabilize a major key while maintaining the melodic sense.
Harmonic Use: Applicable to improvisations on altered major chords, especially in jazz or experimental contexts.
