Dr. Arthur Lintgen can determine which piece of classical music is on a record just by looking at it. His knowledge of classical music goes back as far as Beethoven, so anything by Beethoven or afterward he can identify by the record grooves.

From that, he can accurately pick out which piece he’s reading.
