Step 1 : Introduction to the question "Which classical composer was Schroeder's favorite in the "Peanuts" comic strip?"
...When Charlie Brown walked past a sitting Schroeder in a "Peanuts" strip from the mid-1950s, Schroeder had his ear to a large speaker. Schroeder tells Charlie Brown to "Shh," explaining that he's listening to "…Beethoven's Ninth." As all Charlie Brown fans know, Schroeder was the Beethoven-obsessed musical geek who was eternally irritated by Lucy's interruptions of his practice sessions. Charles Schulz, the comic strip's author, listened to classical and country music as he worked. Source: NYTimes.com
