I don’t know why this drives me nuts, but it does. To quote Rogers and Hamerstein,”A song’s not a song ’til you sing it!” If what you are talking about does not have words, and is not sung, then it’s not a song! It’s a piece!
I messed up that quote! It comes from one of the last songs they wrote together. The whole verse goes:
A bell ‘s not a bell ’till you ring it
A song’s not a song ’til you sing it
Love in your heart wasn’t put there to stay
Love isn’t love ’till you give it away
It’s hard to tell because so many of the notes seem to be missing or inaudible. It might be bad microphone placement. But, yes, the pattern at the end identifies it. I happen to be practicing it these days. It’s much harder than it seems.
