What you should really clarify before you go
For your first dance class in Frankfurt, what matters is not whether you already know some steps, but whether you know what to expect when you arrive. The confirmation often answers practical questions, but sometimes it is unclear whether street shoes are allowed in the room, whether you need to register in advance, or whether partner rotations are part of the class. Clarify these points directly with the dance school instead of guessing the rules.
If you are still unsure whether the class suits your experience level, take a look at the overview of beginner dance classes in Frankfurt. The practical guide to finding a dance school in Frankfurt can also help you choose where to take classes. After that, preparing is just a matter of getting ready for your specific class: plan your route, bring whatever the school requires, and tell the instructor when you arrive that you are new.
You do not need to learn a choreography in advance. In a beginner class, it is normal to watch first, get a feel for shifting your weight, and join in a step later. If you lose the rhythm, follow the instructor and join in again at the next repetition.
