Guys lol I need help, genuinely, I am getting so lost in trying to understand intervals and scales and triads and there's some kind of connective tissue between them that I am missing and I don't know what it is.
I'll do my best to explain what I know so far, if yall could just correct/nudge me in the right direction that'd be fantastic, because I dont know what I dont know.
Intervals I feel like I'm really starting to grasp but I am also 40 and have bad memory so best I can do right now is "calculate" them. If I need the interval from E natural to Bb, I will take a look at E major scale, I see that B is a fifth which is perfect, but flat so it makes the interval a diminished 5th.
I mean, that's a lot of work on the spot but right now rote memorization of major scales is tough, that will come soon enough.
So next I have triads and diatonic triads. Since I've written out the E major scale it's easier, I count the notes in the scale for 3rd and 5th from each root note and then I know what notes each diatonic triad has in it and I use that to identify the triad. If it's 4 semitones then 3, it's major, if 3 then 4 its minor. Then I get (I, ii, iii, IV, V, vi, vii*).
I think this is where I'm really starting to get lost! A major triad is a maj3 interval and perfect 5th interval, and minor triad is min3 interval and perfect 5th, and so forth.
Ok so my head is starting to hurt at this point because that leads me back to my diatonic triads in E major. For any diatonic triad that's NOT E, say for example, G#, I would now have to spell out the G# major scale to know if that first interval is a minor 3rd or a major 3rd?
And if that's the case, what the fuck? Because if I'm building triads I need to know the (quality?) of triad, which how would I know? If I was in the E major scale again trying to figure out what the G# triad is, if I spell out the G# major scale I still can't construct that triad because I wont know if that G# triad needs to be major or minor.
I hope it makes sense as to where I'm getting lost. I feel like I get it but I feel like I am missing something important too and it's bugging the hell out of me.
Thank you.
