As someone who has also studied classical composition, I have have found learning to create music using electronics and sequencers to be a huge mental challenge breaking out of everything I’d been taught, but simultaneously liberating for that very same reason – the fact I don’t have to think in the same way about melodic variation and harmonic development: the sentence, period, antecedent, consequent, root motion, functional harmony, and of course ending phrases with some kind of cadence which is perhaps the most classical signifier of all.
It’s also kind of hard to break out of functional harmony, this idea of the tonic–dominant relationship which governs everything. When I listen to a lot of my favorite electronic artists, there is almost no functional harmony to speak of. Chords just do whatever sounds cool in the moment – and chord motion is comparatively way more minimal. Even at a drop or end of a section I almost never hear anything I would call a dominant to tonic motion. There’s no phrases and no cadences. Sometimes it’s hardly tonal at all – mostly focused on textures and sound design.
I also feel like most (good) electronic music, when it does use harmony, is in some kind of minor key, often ambiguously so. Minor modes like aeolian, phyrgian, and dorian. I rarely ever hear the raised 7th or 6th. I also feel like harmony is less triadic and definitely not so much of a propulsive motion that we’re used to in classical composition.
Regarding form, are you familiar with the term through-composed? In my own orchestral work, that approach has always appealed to me for the abandonment of sectional structure, traditional development and repetition. I guess it’s a little more of a 20th century approach onward. Interestingly, most popular music is not through-composed, obviously having some kind of ABA / verse-chorus structure with repetition and contrast; but so much electronic music to me is essentially “through-composed” even if no one is thinking in that term. Just like you observed: they take a palette and kinda just move through it on a journey, without much concern for repetition or structure, and definitely no requirement to land back “home” to any kind of musical motif or tonic. Of course there’s more pop-oriented EDM that takes on a developed structure, but I’m not really talking about that and it sounds like you’re not either.
I don’t have any advice myself as someone navigating the differences, but just wanted to say I come from a similar world and am still trying to reconcile the two approaches. If you presumably do score study and analysis, why not do the same with electronic music you enjoy? Obviously there’s no score to follow but I’ve been doing this lately, writing down my observations around structure and what I like. I think it’s been helpful.
I was listening to an electronic track the other day which I noticed is two chords a 3rd apart the entire time (IIRC), but they don’t really belong to the same key, and they were given equal weight so it was kind of ambiguous to tell what “home” could be. The bass line had some rhythmic variation here and there but functionally speaking was the same the whole way. On paper this description sounds boring but honestly I never got bored because the way they add and subtract elements and textures over that “harmonic” bed. So for me I’m trying to let go of some of my classical impulses and allow myself to explore music in that way.
Good luck!
