Im a skater for G.Britain and i've had tom make up a tango for an O.S.P (original, set, pattern) dance.
The things that I've learnt through this experiance is that you need good, strong music(music with a beat)something you can express yourself with and you need the emotion of a tango in you yourself to be able to perform the dance. My top tips for performing a Tango:1)choose your music wisely 2)Always try and think of original movements if nothing comes to mind cheat and try a website like www.dancevision.com to test a video. 3)To perform well think about Tango's p'haps learn about the background and what country/countries it may have come from. 4)Put the Tango in yourself, get into the mood. 5)Express yourself eg:
Put on a stuburn face, Use expressive body language and Use you arms and fingers to make you more watchative.
