Blues is traditionally an African American dance that can either be danced with a partner or alone; Solo Blues is for the latter. It came from North America in the early 20th century and became known in Europe in the 1920's. It's a smooth dance style with sensual moves and slow steps and plenty of room for improvisation. Most of the dance moves were inspired by traditional blues music, but it can be danced to any tempo as long as it has a 4/4 rhythm.
