This system focuses on intervallic hearing. The process of translating music that is heard. Refers to the scales that are displacements of the major scale. A chord containing three notes, usually consisting of a root, a third above the root and a fifth above the root. A chord containing four notes, usually consisting of a triad with a seventh above the root.
Tensions are notes added to a seventh chord by extending the chord upwards in thirds.
Not every tension will work with every chord type. A series of dominants without a direct key relationship, each one resolving down a fifth to the next. Borrowing chords from a parallel mode. In Harmony 2, borrowing chords from natural minor to use in the parallel major. Their expected resolution is down a minor second.
