whats the advantage of harmony/chords? what do you think it brings to the table that you wouldn't get with just a melody line and a drum part? are chords just used to add some more texture to a song?
you'll have to try it with and without, and see for yourself. it's kind of like what color does to a picture. it usually doesn't change the story line or the items in the picture but wowie, it makes things feel better. and the viewer doesn't even quite know why
