This might be yet another n00b question but..... whatever, sigh
How exactly do you all write melodies, chord progressions, baselines, and all the other individual "components" in a song? Again, I often seem to have problems with writing melodies myself, as often or not, they just "don't work." I mean, I've read a lot of the "theory tips" that explain some of the "rules" that help you with this sort of stuff, but even then, just getting an idea down seems to be the most difficult part of the process.
Also, which are you supposed to get down first. The chord progression, or the melody itself?
