Yeah, makes sense about major/minor in terms of tension and resolution.While Dorian, Lydian and Phrygian modes do offer symmetric tetrachords (i.e., patterns of whole and half steps), they did not lend themselves as effectively to the functional harmonic structures that characterized later Western music. The tonic-dominant relationships that became central to Western tonal music were less straightforward in these modes.
Harmonic practices, including the use of triads and functional harmony, favored the major and natural minor scales. The Ionian mode, with its strong tonic-dominant relationships, became is foundation for tonal music.
The shift towards Ionian and Aeolian modes in Western music was a gradual process influenced by historical, theoretical, and aesthetic factors.
Theorists in the Renaissance began to formalize the concepts of tonality, emphasizing the importance of the tonic and dominant relationships, which are most clearly defined in the Ionian and Aeolian modes.
While Dorian and Phrygian modes were part of the musical lexicon, they did not fulfill the evolving needs of Western music in terms of harmony and expressiveness in the way that the major and natural minor scales did.
The result was the establishment of a tonal system that prioritized these two modes, shaping the direction of Western music for centuries to come.
And thank you so much for the chord functions.
I’m going to save a copy and put it to practice in the next few days. See what the chords sound like in different functions.
