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!
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.
