Cuban rumba is the Afro-Cuban root under a lot of what gets danced socially — guaguanco, with its playful chase between partners, is the form most people mean. It's more folkloric and improvisational than salsa, often danced solo or in a circle rather than in closed partner frame, and it shows up in Cuban-style scenes and workshops more than on the general social floor.

Rumba is best learned in an Afro-Cuban or Cuban-style workshop, not a standard salsa drop-in — the body movement and the rhythmic feel come first, before any partner figure. Treat it as a complement to casino rather than a standalone social night.
