Repetition of basic knowledge is actually a big part of a successful education, Even schoolkids in the earliest grades can actually learn surprisingly complex subjects by heart simply by blabbing everything back word-for-word. Problem solving skills can then be built up on these basics.
We used to have these questions about "What are the advantages and disadvantages of X?"
I used to think I was outsmarting "the system" by only learning a few key facts about X and then twisting them around to get advantages and disadvantages, but little did I know that was the whole point of the course — to see the same thing from different perspectives and realize there are both advantages and disadvantages to X.
I am not convinced by that. Kids tend to learn problem solving (and other) skills if given a chance. i do not think encourage huge amounts of rote learning is an optimal, or even, useful say of doing that.
My experience (with myself and my kids) has been the opposite.
Making music would suck if I hadn't spent years of (fought against every day) practice/rehearsal. We need to practice learning the tools, not just understanding we have them. So many rote things opened so many doors for me to explore later.
My creativity would be way less if I hadn't spent hours listening to others music. I think it applies to less fun/interesting things as well.
