User:VectorGraphics/Earth-22 Theory: Difference between revisions
Created page with "Earth-22 uses the system of 22 equal divisions of the octave, and the Pajara[10] scale. == Early history == Middle-Eastern music relies more heavily on pentatonic subsets of diatonic, most "purely" directly tuned "trichords". In the West, this is borrowed into European music theory, where for a while, music is tuned to the four church modes of Pythagorean pentatonic: Lydian (in our world, major pentatonic), Mixolydian (in our world, Mixolydian pentatonic), Dorian (in o..." |

As for chord functions, the essential form of a chord consists of the root and the 8-step ("fifth") above it, which can alternatively and somewhat more discordantly be voiced as a 2-step dyad, similar to the minor or major third dyad in our music. Triads similarly span an 8-step in the default voicing or a fourth in an inversion. Thus, there are two "rings" of chords connected by mediants. | As for chord functions, the essential form of a chord consists of the root and the 8-step ("fifth") above it, which can alternatively and somewhat more discordantly be voiced as a 2-step dyad, similar to the minor or major third dyad in our music. Triads similarly span an 8-step in the default voicing or a fourth in an inversion. Thus, there are two "rings" of chords connected by mediants. This means that functional harmony derives from the opposition between the two rings of fifths, and so chords sharing a function tend to differ by 2-steps rather than 3-steps. Thus, we have the tonic (1, 3, and 9) and dominant (5 and 7) functions opposing the antitonic (4, 6, and 8) and antidominant (2 and 10) functions, although the dominant function acts more like our world's subdominant, and the role of our dominant function is split into the antitonic and antidominant; the 4 functions are generally thought of in terms of stability vs. instability, and stasis vs. progression. | ||
