Ah, so I did read the context correct.
In drumming, both Haskall Harr and Wilcoxen are rudimental method books, that accomplish basically the same thing, but Harr is stuffy/strict military style no matter how you “interpret” it and Charlie Wilcoxen just swings on it’s own (even while marching down the street).
Benjamin Podemski and Morris Goldenberg are the ancient, accepted, standard “classical” snare drum methods circa 1955 and still SOP (why reinvent the wheel?), but to me Podemski is like doing math drills and Morris’ (often pronounced “Maurice” like Stevie Miller’s Space Cowboy) “Modern School for Snare Drum and Guide Book for the Artist Percussionist”, has charm and substance while getting the job done.
As a bass-player, i have GREAT respect for drummers who do it right!
I love “Charm and Substance” that gets the job done! :-)
