Dance and Singing (Frankfurt)

Hello everyone! I'm thinking of joining dancing and/or singing lessons. Any tips?

I have done Videoclip Dance before, so I'm looking for something similar or modern, jazz, etc... nothing professional, just for fun...

Also... singing! I have studied singing for some years now, so I am looking for a choir and/or teacher (this time something semiprofessional or good quality). Preferrably classical stuff, I could try modern, but my technique is totally classical.

Thanks for your advice!
