Heretical app idea: I want to make a football playbook-style guide to the various tango dance steps.
This is heretical, because tango is deeply improvisational. But it does have a language, and learning the words is important. The grammar too.
I've got a decent collection of sequences that I am comfortable initiating and moving between, but I honestly don't remember them all in the moment sometimes. I want a flash card of options and useful sequences, space allowing in the flow of dance.
