Willson was born in Mason City, Iowa, to John David Willson and Rosalie Reiniger Willson, and he had a brother two years his senior, John Cedrick, and a sister 12 years his senior, the children's author Dixie Willson. He attended Frank Damrosch's Institute of Musical Art (which later became the Juilliard School) in New York City. He married his high school sweetheart, Elizabeth "Peggy" Wilson, on August 29, 1920. A flute and piccolo player, Willson was a member of John Philip Sousa's band (1921-1923), and the New York Philharmonic Orchestra under Arturo Toscanini (1924-1929).

His work in films included composing the score for Charlie Chaplin's The Great Dictator (1940) (Academy Award nomination for Best Original Score), and arranging music for the score of William Wyler's The Little Foxes (1941) (Academy Award nomination for Best Music Score of a Dramatic Picture). During World War II, he worked for the United States' Armed Forces Radio Service. His work with the AFRS teamed him with George Burns, Gracie Allen and Bill Goodwin. He would work with all three as the bandleader, and a regular character, on the Burns and Allen radio program. He played a shy man, always trying to get advice on women. His character was ditsy as well, basically a male version of Gracie Allen's character. In 1942, Willson had his own program on NBC. Meredith Willson's Music was a summer replacement for Fibber McGee and Molly. Sparkle Time, which ran on CBS in 1946-47, was Willson's first full-season radio program. Returning to network radio after WWII, he created the Talking People, a choral group that spoke in unison while delivering radio commercials. He also became the musical director for The Big Show, a prestigious comedy-variety program hosted by actress Tallulah Bankhead and featuring some of the world's most respected entertainers. Willson himself became part of one of the show's very few running gags, beginning replies to Bankhead's comments or questions with "well, sir, Miss Bankhead . . ." Willson wrote the song "May the Good Lord Bless and Keep You" for the show. Bankhead spoke the lyrics over the music at the end of each show. He also worked on Jack Benny's radio program, and hosted his own program in 1949. For a few years in the early 1950s, Willson was a regular panelist on the Goodson-Todman game show The Name's the Same. In 1950 Willson served as Musical Director for The California Story, the Golden State's centennial production at the Hollywood Bowl. Through working on this production, Willson met writer Franklin Lacey who proved instrumental in developing the story line for a musical Willson had been working on, soon to be known as The Music Man. The California Story spectacular was followed by two more state centennial collaborations with stage director Vladimir Rosing: The Oregon Story in 1959 and The Kansas Story in 1961.
