Minor chords make a lot more sense when you consider the 5th the actual root and basically view them as upside-down major chords.

Major, e.g. C: C, E (= C * 5/4), G (= C * 3/2) or 4:5:6
Minor, e.g. C⁻: C, Eᵇ (= C * 6/5), G (= C * 3/2) or 10:12:15
Minor, in relation to the 5th: G, Eᵇ (= G / 5/4), C (= G / 3/2) or 4/5/6

C⁻ should really be called G⁻.

deleting and re-sending a toot because I fucked up the numbers... twice :')

@ki (just a heads up that you seem to have triple tooted this toot)

@bazkie
thanks, I used a "delete and rewrite" function of my client that might not have deleted the toots correctly :')

@ki whoops!

@bazkie
welp, sometimes you make a mistake, try to fix it, make three more... business as usual :D

@ki well better too many toots than too few!

@ki make it more interesting by forming 5 note chords which are minor and major
Show threadfunbaker; Je suis Antifa2d ago
@ki then make some of them suspended by inverting the right notes

@funbaker
- inversion doesn't change ratio notation
- a sus4 triad is (4/3) : (3/2), so 6:8:9 (otonal) and 8/9/12 (utonal)
- a sus2 triad is (9/8) : (3/2), so 8:9:12 (otonal) and 6/8/9 (utonal)
- tetrads and pentads are basically stacked triads, I'll leave the calculations up to you, have fun. it's just prime factorization
- an interesting side effect of stacking triads is that a major 7 is 8:10:12:15 and 8/10/12/15, while a minor 7 is 10:12:15:18 and 10/12/15/18

(calculations done in my head after 1 am, there might be a mistake or two)

@ki tbh I dont understand anything of that, I just like to play with Intervals
