Thanks a lot. May you explain me, how "it should be free and mold breaking unlike the structured and rigit style Kosei was used to" turns into "he makes the rules rather than obeys any existing rules"?
My questions :
1. It should be free - what is `it` and why is it `free`?
2. mold breaking - I translated that `break the mold` is `to stop doing something you used to and do something very new`, but it makes no sense for me with other parts of sentences.
3. unlike the structured and rigid style Kosei was used to - I would say that `mold breaking unlike the structured and rigit style Kosei was used to` means `stop play piano dull and worisome as he used to and start playing vigorous` or somehow like that. But he haven't play since instructor's death, so about what are `Kosei was used to` and `structured and rigid style`?
