Kinda Like Beethoven But

Karkat Vantas, an English studies college freshman in need of some extra cash, auditions and gets accepted as the sole cellist for what seems like an easy, decent-paying recording job. The music was sent to him, he recorded it, and he shipped it back to the sender; and, then, he assumed he was finished. Two days later, he received another packet of almost identical sheet music and more recording supplies. Again, he recorded himself and sent it back. However, when a third package of recording supplies and music arrives, he decides to investigate further; and, what he finds is everything but what he expected. (In case you don't read the tags, it's a deaf!Dave/Karkat fic. Yay?)
