I know nothing about choreography and don't even have the confidence to perform for my partner
I think listening to a lot of ME music can help you to understand choreographies; once you can hear accents, rhythms and instruments it becomes a bit easier to tune into the music and express it through your dance.
I have been having 2/3 lessons a week for a year and a half and I read books and watch videos of Belly dance on youtube etc. and I listen to ME music more than any other music.
Great - keep it up!
My teacher has suggested more training before I perform; she says my technique is good, but my ability to perform needs work which I agree with (I am still very self conscious about doing moves right/wrong and find it hard to relax and just enjoy it).
