I agree that EVERYTHING we do originates in the brain... but the it is also true that the brain addresses the same topic differently if it sees it as a logical question or an emotional one.

Studies show more left brain activity when solving analytical problems, and more right brain activity when involved in playful or emotional activities.

Creative decisions based primarily on a formula (such as musical scales) would probably stir the left brain... whereas creative decisons made "because it feels right whether it fits the formula or not" would probably be driven by the right hemisphere.

Whether this is a moot point or not becomes most important in the teacher-student relationship because research has also shown that people learn more easily from teachers whose teaching style matches the student's learning style
