I'm trying to put the finishing touches on a song and wanted to know if anyone could help me with this. I don't know how to speak theory very well so sorry if it isn't entirely clear. Can the bass be playing a note that's in the right key of the song but never lines up with a guitar chord that also has a B? For example my bass line starts on B. The guitar progression starts with D#G#A#(low to high) but the bass B never lines up with a guitar chord that has a B in it as that progression goes on. Is this kosher or does this fall into the category of "its music so do whatever as long as it sounds good"?
