Transcript:
Schroeder sits smiling at Charlie Brown who is standing over a toy piano plinking out notes. The latter says,"See how easy it is, Schroeder?"
He sits and continues to plink. He says,"The piano is a beautiful instrument if played properly"
He stands up and gestures to Schroeder. He says,"Now let's hear you play, huh, Schroeder?"
He blushes in embarrassment as he sits across from where Schroeder is playing complex classical pieces on the piano.
Trivia:
The first time Schroeder plays a toy piano. The piece played is actually by Rachmaninoff, not by Beethoven
Original comic:
It's pretty fun to play too. It looks a bit daunting but the easy parts (the first few pages) are not that bad and it's easy to make sound great.
