I like music too, thats why I post here. I can't play any kind of instrument I am left brained mathematical so I assume I'm trying to balance it out. Now my Mom can play the piano and has never been trained on it kinda strange.
I've once met a person, who told me that he didn't like music at all. I can appreciate the silence and nature sounds as well, but only this? Pretty hard to imagine...
Nothing wrong with seeking new challenges, but in general, I believe that you are who you are, and being good in math is a true contribution to society.
I went backstage during the break of this band (my dad knew a few of their members) and we've found out that several band members had never learned a note, the rhythm was simply in their Brazilian genes.
