mx SRB2r, i elaborate:
"the cult of the chord progression" is what i call the pervasive belief among numerous people in creative circles i am adjacent to that more complicated chord progressions are always better that simpler ones. this usually comes as a package with the more general belief that complexity in music is always better than simplicity. you see this especially among the terminally theorybrained who are in an endless competition to one-up each other by filling their music with modulations, polyrhythms, virtuosic instrumental performances, and so on. (to generalise, you might call it "the cult of complexity" - or, more snarkily, "the cult of berklee").
the truth is that none of that stuff matters because all that really matters is whether music has the juice, but unfortunately there is no reliable way to get the juice into your output besides strange, blind, wordless intuition which can appear and disappear uncontrollably. this is so frustrating it makes you want to kill yourself, so people search desperately for One Weird Trick to getting the juice flowing - "fill your music with ✨jazz chords✨" is one such Weird Trick.
if your music does not already have the juice, adding modulations and chord substitutions and so on to it won't help because the juice is not in a chord progression, it's in you.
what i'm really trying to say is beware of One Weird Tricks in general. there is no secret to creating art - if there was, it would not stay a secret for long. the low-hanging fruit has all been picked. if you want to find beauty, you will have to climb for it.
with all that said, please bear in mind zor's wise words from earlier in this thread - if you think the shit i make sucks, disregard all of the above.
