Most abstract painters such as Picasso and Dali had mastered the brushstrokes of life-like classical painting before departing from its rules to create their own styles.
Most jazz musicians like Miles Davis and Louis Armstrong were trained in the theory of rigid classical music before they could create their own signature improvisation styles.
Meaningful creativity requires a mastery of fundamental constructs before deciding to depart them. Once you know the jungle well enough, you can discard the map and trace out your own paths.
