Accordion appeared in popular music from the 1900s-1960s. This half century is often called the "Golden Age of the Accordion". Three players, Pietro Frosini and the two brothers Count Guido Deiro andPietro Deiro, were major influences at this time.
Most Vaudeville theaters closed during the Great Depression, but accordionists during 1930s-1950s taught and performed for radio. During the 1950s through the 1980s the accordion received significant exposure on television with performances by Myron Floren on The Lawrence Welk Show. In the late 1950s and early 1960s, the accordion declined in popularity.
In popular music, it is now generally considered exotic or old-fashioned to include the accordion, especially in music for advertisements. Some popular acts do use the instrument in their distinctive sounds. A notable example is Grammy Award winningparodist "Weird Al" Yankovic, who plays the accordion on many of his musical tracks, particularly his polkas. Yankovic was trained in the accordion as a child.
