A little like how Fozzie Bear and Miss Piggy are rarely seen together (although for different reasons), you rarely see Linus and Schroeder in the same panel. As for why Linus reminds Schroeder of Beethoven, your guess is as good as mine.
The characters in this strip are solidly "Classic-era" Peanuts. The only characters who still have a bit of developing to do are Charlie Brown (whose thick oval eyes still reminds us a bit of earlier strips) and Snoopy (who so far has developed the least).
