In order to study songstructure, i'm trying to learn by ear and recreate the dark world theme from zelda. If you don't know it, this is it: https://www.youtube.com/watch?v=sslj06K-Nlw The bassline is fairly simple to figure out by ear, as is the lead. The chordline is giving me trouble though. What i'm trying to do is listen for the root of every chord, and then combining each root with something, like a fifth or major or minor third and so on, see what fits. (i guess they technically aren't chords). Right now i'm stumped. This is what i have so far: Ignoring my less-than-perfect playing, it sounds 'sort of' right, i think i got the roots right. But something feels off in the progression i've got so far. Plus only half of it's done of course I wonder if there is a different way to approach this? Some way to figure out the chords once you've got a bassline and a lead? Something along the lines of 'well, this song is in the key of x, therefore this chord here has to have a major third, and that chord there can't have a fourth' perhaps? I am woefully lacking in theoretical understanding. Or is it a matter of developing my ear, and having chosen a poor song because it is simply hard to hear due to the low synthquality? Just to clarify; I realise i could import the midifile and get the exact part that way, but my goal is to learn how to analyse songs better, not necessarily to finish this particular one.
