brazil music

Hi. I need some help on information about Brazil. It’s a project I’m working on. I’m looking for info that only locals would know or any travel stories would be cool too.
So, I need some help about the following:

The people:
– What are they like? (please don’t just say “friendly”)
– How to they act with foreigners/visitors?
– How do teens in Brazil act? What do they do for fun?
– How do people greet each other? Gestures, actions etc.
– What’s the social scene like? Nightclubs, night life; dating etc.
– Any other facts would be great.

The Place:
– Beaches – what are they like? What’s the surf like? Best places to surf?
– Climate and weather?
– Need info on Salvador most especially, but info on Rio, Copa, Sao Paulo or anywhere else would be great too.
– What are the towns/cities like?
– Places for sightseeing? Trendy places, shops?

Culture and Food:
– Any traditional customs?
– How do people dress normally? What’s considered casual / formal?
– Local dishes / delicacies? Common snacks etc.
– Carnival – where is it usually held? What does it involve? What do you see?
– Music and dance ~ what kind of dances? What music?

Sports:
– How big is capoeira really? Can you see locals doing it on the street, on the beach or wherever?
– Football? Street soccer? Who, what, where?
– other commonly played sports?

I think that’s all I need at the moment
Thanks to all who help!
