American Style Ballroom

Used mostly for social dancing, the American style of ballroom
dancing was developed by major US studio chains, such as Fred
Astaire. American style dancing, features underarm turns and open
work where the partners can separate from each other and dance in
open positions. For example, the rise in the American style waltz
remains mostly vertical and is felt mainly through the legs and
ankles; the International style waltz uses a different rise.

Both American and International style ballroom
dances are divided into the following categories:

Rhythm

Bolero | Cha-Cha | E Coast Swing | W Coast Swing | Hustle
Lindy Hop | Mambo | Merengue | Polka | Rumba | Salsa
Samba | Two Step | Jive | Paso Doble
