But there is additional inconsistency, not all sevenths stacked the above way have a unique quality. Triads are built upon stacking min/ maj thirds, while sevenths can be subdivided into qualities built upon staking min/ maj thirds, and those that also include dim/ aug thirds. If we have a look at the status of contemporary qualities, as a theorist, we are a bit in the twilight zone. Here, I don't think that you should say that the ♭5 belongs to the "triadic portion of the chord", but rather that it is an alteration of the underlying chord quality. Here, the underlying chord quality (major, minor, diminished, augmented) comes first, then the highest degree of upper structure (7th, 9th, 11th, 13th), and finally added pitches or alterations (sus4, add9, ♭5, ♯9, etc.). Such a chord may be written as C7(♭5), or C-7(♭5) for example. "♭5 chords are a thing, particularly in the 'triadic' portion of dominant chords." Sure, ♭5 chords are a thing, but here the ♭5 is considered an alteration. These days some people talk about sus4 triads and Lydian triads, for example. That does not mean that C, E and G♭ can't be used together, and you can make up your own "triads" if you wish. Minor 3rd + minor 3rd -> diminished triadĭiminished, doubly diminished, augmented, and doubly augmented thirds are just not used to build the harmonic structures called triads in traditional harmony. The list of triads generated in this way is short: The triads found in traditional harmony are built by stacking major and minor thirds. (Perhaps because classical theory was well-established before jazz came about?) What is it? Or am I missing something? ♭5 chords are a thing, particularly in the "triadic" portion of dominant chords, so I must guess that there is some historical reason why they aren't considered triads. I'm sure someone is going to think, "Ah, but triads are constructed by stacking thirds, and the distance from a major third to a diminished fifth is a major second."Īnd I would say, "Well, if you look at an example like C-E-G♭, it seems to me that E to G♭ is a diminished third, not a major second." However, the last remaining combination-major third/diminished fifth-is simply ignored, overlooked, or perhaps purposely excluded from triadhood. Of the two which remain, the minor third/augmented fifth combination results in another major triad in 1st inversion. While both devices are very similar, they have some essential differences that will impact your product choice for specific needs.If you look at the kinds of thirds and fifths, you immediately see six obvious combinations:įour of these comprise the complete set of so-called triads: The main differences between Omron M2 vs.
