Where can i find information on the type of music that is used for ballroom dancing?

Question

And the kind of costumes that they were?

Answer 1

For music, go to www.ballroomdancers.com and listen to the music samples. If you need precise information on what tempos they use, go to www.usabda.org and find section "Rules and Bylaws"

For costumes, there are two types of costumes: something you wear for practaice or social dancing, and the other kind is something you wear for competitions. For practice, you can wear something comfortable and reasonably nice looking, or check www.dancesport.uk.com for really cool practice wear. For competitions, go to any competition website and just look what people wear. For beginner competition, people wear practice clothes. For advanced competition people wear costumes.
