In the final chorus of when i get older there are subtle instrumental bits that go simultaneously with the singing, like a piano ish sound for instance. Those are of course present in most parts of the song, but the ones in that part seem particularly effective. Is there a name for this technique? How do you tell if the backing instrument will add to or detract from the main melody?
it's kind of like trying on clothing. it's exactly like trying on clothing, actually. try something on .... see if it's good ..... try something else on ....... etc. if you do this for a little while, pretty soon you should look great
