I had a go at one of Patterson's courses online.
It was wonky & hokey.
Insisting that the only syllables that should be counted in a consideration of prosody were the "stressed" ones.
Lots of stuff like that through out.
He would also take an example song - one by a student - a song with some quirks, individuality and he'd make the student change things bit by bit & one by one until it was generic and smooth.
NOT recommended unless you want to follow rules and join a herd.
