Okay, I know you don't know what D to H means. It may as well be Dead to Him. But in this case, it's rehearsal letters, and it's in the I like to play jazz movement.
When first we come in, Amy is trading colors and licks with the winds, and since it's one of the few ways I know how to end a section, there's a big downward flourish. Because, uh, it's what I do.
And then it's the low sinister jazz music, which has a lot of repeated notes. Sorry about that, Amy.
This is, as always, provisional. And Amy is takin' names.
