Q: what if i have an idea for a part of a song, say just chords and melody, but it doesn't work, or i don't like it. what if it would work if i add bass, or drums, or another section, or cool sounds? if i'm writing a song before adding those things, i'll never know if they would justify a given off-kilter idea. does that mean i should accept that i'll never write a song that isn't fully functional with just chords and melody?
A: there's a lot of different ways to do it. if you feel like you're missing out on a certain angle, you can do it a different way. you could make some grooves first, to see if that gets you somewhere
