Cornwall is a region in southwest England which has been historically Celtic, though Celtic-derived traditions had been moribund for some time before being revived during a late 20th century roots revival.

Cornish musicians have used a variety of traditional Celtic instruments, as well as imported mandolins, banjos and accordions. The bodhrán (crowdy crawn in Cornish) has remained especially popular for years.

Cornsh dance music is especially known for the cushion dance from the 19th century, which was based on an old tune adapted for French court dances.

Cornish music festivals called troyl were common, and are analagous to the closely-related fest-noz of the Bretons.
