I actually do appreciate this teaching style, as long as you do put notes to the established theory and terminology at the end.

It's like that popular Monad tutorial that has you implementing Functors and Monads in order to solve a problem without ever telling you until the end that what you just created were Functors and Monads.

Starting off with the well-known terminology kind of colors the discussion from the beginning--even folks who don't really know what harmonics or timbre or monads or applicatives are probably have some general impression, and that impression could be wrong in a way that prevents them from learning.
