His music was conservative, concentrating mostly on standards, polkas, and novelty songs, delivered in a smooth, calming, good-humored easy listening style. His show was warm and family-oriented. His "Champagne Music" has been considered the epitome of "square".
During the 1930s and 1940s, Welk led a travelling big band, specializing in dance tunes and 'sweet' music. In 1952, Welk settled in Los Angeles, California. In 1955, he began producing The Lawrence Welk Show.
Welk's television program had a policy to only play well known songs and tunes from previous years, so that the target audience would only hear numbers that they were already familiar with. This strategy proved commercially successful. His TV show show was recorded as if it were live and was sometimes quite free-wheeling. Welk often took ladies from the audience for a turn around the dance floor. During one show Welk brought a cameraman out to dance with one of the ladies and took over the camera himself.
The reputation for "corny music" notwithstanding, his musicians were always top quality, including accordionist Myron Floren and New Orleans Dixieland clarinetist Pete Fountain. Welk was noted for spotlighting individual members of his band and show. His band was well-disciplined and had excellent arrangements in all styles. One notable showcase was his album with the noted jazz saxophonist Johnny Hodges. Welk's instrumental cover of the song "Yellow Bird" was a hit.
