I do have to question under what authority these musicologists declare Suzuki’s method as fraudulent, especially since we have seen empirical results that it makes good musicians. After all, most musicologists were tutored under the same liberal arts claptrap which indoctrinates its practitioners into Marxism and feminism, all while giving its degree holders crushing debt.
Practice makes perfect, and rote memorization is one of many necessary tools to make a good musician/student. Liberal education ‘theorists’ have started ranting against rote memorization, perhaps because its usage reveals that some students are better than others.
The Suzuki method isn’t designed to create great musicians but to let everyone learn to play to the best of their ability.
