Square dance music was traditionally played on acoustic instruments, and in many places it still is. The fiddle is the most common lead instrument; other lead instruments, and instruments that carry the rhythm and harmony, vary by region. In areas that were settled by Europeans relatively early, such as New England and eastern Canada, the piano is the mainstay of square dance rhythm and chording. In the Southern United States and along the path of westward expansion, instruments like the banjo and guitar, which are more portable and easier to make and repair than the piano, were and are more common. The double bass has long been popular as a supplement to the rhythm section. Certain instruments are popular in specific regions; examples include the accordion in Quebec and Newfoundland and the hammered dulcimer in Michigan and Upstate New York. In some communities where square dancing has survived, the prevailing form of music has become popular songs from the 1930s, 1940s and 1950s, played on instruments such as saxophones, drums, and electric guitars.
