That was the last room you had not stood in. You have now stood in all sixteen, and the balcony heard a rising arpeggio. There is a hook on the second balcony with your id on it.
You are not in one now. You were played at your usual pitch.
Now and then the floor drops, and everything played is an octave lower until it comes back up. Nobody starts it and nobody can stop it. It is there for the people on the balcony.
You cannot wait for a drop. You either arrive in one or you do not. Of your 18 requests tonight, 0 landed in a drop.
You were heard as a kick, with a rising arpeggio for finishing.
