def depends on what one is going for in ones music. its why i find a lot of melodic techno a bit too formulaic these days, because the format and the sound palette seem kind of restrictive to just give people what they want all of the time. its fun and i dance to it and make it sometimes, but i never want to veer into ‘obnoxious forced melodrama’ (as one 'naut put it) just because thats what the genre ‘requires’
a friend of mine put it well - set your track apart from the rest with a few really unique things (polymetry, scale, fills, blue notes, timbres, modulations, arrangement, whatever means unique to you), but dont pile ‘uniqueness’ onto every single element of the track or it becomes too hard to follow. your brain needs at least a few elements that are consistent and predictable, whether or not that’s the structure
so yeah, finding a balance between predictability and intrigue/offroad territory to keep both the body and brain hooked in, to make something that’s danceable (if you intend it for club use) but also memorable and unique past the summer.
