The implication, however, is that he played a wide variety of pieces from the classical music cannon.
Here are some examples of what Schroeder might have played based on the comic strip:
* Beethoven: He was known for playing Beethoven's "Für Elise" and is even seen in the comic strip playing a piece that sounds like it could be "Symphony No. 5."
* Mozart: There's a strip where he plays a piece that sounds like it could be from "The Marriage of Figaro."
* Bach: He's also shown playing music that sounds like a Bach fugue.
Remember, these are just assumptions based on the comic strip's portrayal of Schroeder's music.
Charles Schulz, the creator of Peanuts, did not specifically state which pieces Schroeder played. This allowed readers to imagine their own favorites, adding to Schroeder's enigmatic charm.
