I study the lyrics and melody of my music too. It’s nice to know what the song is about, how many verses, chorus, and breaks are in the song. This is really helpful for building choreography and knowing when to repeat moves. Not to mention musicality! If you know your music front and back you’ll be a lot more confident dancing to it!
I try to start most of my dance workouts with a simple two count move like a slide or step tap. This gives me an opportunity to preview what’s coming and build confidence in the class. I want everyone to leave feeling successful!
I totally use notes and yes I totally throw a song into a class from time to time and wing it. I don’t recommend doing this very often and definitely avoid this method if you’re not comforatble with creating choreography on the fly. Because when you bomb you bomb hard. If you’re lucky the moves will come naturally and it will ROCK. If you’re okay with possibly eating some humble pie then go for it.
