When Robyn says "ok", it's two slower notes going down. When Joanna and May appear it's two or three fast notes going down. The part where tyrian disappears sounds like two notes going down. Tyrian on the rafters is two slow notes. The part where May uses her semblances sounds like a mess of fast notes. When Robyn confronts Blake and Yang, the two notes going down again.

As much as I love the idea of hinting through music, I'm sorry to say I think you're wrong, Phantom. I think it's just a "something bad and/or suspicious is happening" noise. :P
