Schroeder Played Real Beethoven in Charles M. Schulz’s ‘Peanuts’ Strip

I didn't know this but I suspected it was true:

When Schroeder pounded on his piano, his eyes clenched in a trance, the notes floating above his head were no random ink spots dropped into the key of G. Schulz carefully chose each snatch of music he drew and transcribed the notes from the score. More than an illustration, the music was a soundtrack to the strip, introducing the characters’ state of emotion, prompting one of them to ask a question or punctuating an interaction.

You've seen those Peanuts' strips, haven't you? Where Schroeder is playing a piece of music and the music notation appears in the air above him? Well, you can now tour the Charles M. Schulz Museum and Research Center and view a collection of panels of those strips and listen to the music in those panels on headphones. An added dimension to Schulz's art.

Interesting.
