OOC: The Orchestra
Tom was probably a bit late and a bit awkward about setting up his cello. He had a bit of trouble reading the music so he set up close to Millicent because it was always easier to see, with a piano, what key they were meant to be in and that helped him get sorted.
He would have scribbled a lot of notes on his music, writing in the flat and sharp symbols instead of just trusting himself to remember.
