Septimus, not sure if you've heard of this, but music according to scientific reports have shown to improve ppl's thinking in math and overall all brain activities (like what Hmoll said) due to the fact that your left brain (left brain takes care of mathematical and logic stuff) controls your right hand, and your right brain (controls artistic stuff, creativity i think) controls your left hand, so when you play piano, you havta work 10 fingers at a time, which logically should be improving your brain skills
