Because old-time fiddle-based string band music is often played for dances, it is often characterized as dance music. However, there are also long-standing traditions of solo listening pieces as well as fiddle songs, such as those that have been documented in West Virginia by Erynn Marshall in "Music in the Air Somewhere: The Shifting Borders of West Virginia's Fiddle and Song Traditions" (WVU Press, 2006). In dance music as played by old-time string bands, emphasis is placed on providing a strong beat, and instrumental solos, or breaks, are rarely taken. This contrasts with bluegrass music, which developed in the 1940s as concert music. Bluegrass music, however, developed from old-time music, and shares many of the same songs and instruments, but is more oriented toward solo performance than is old-time music.
