Whenever I listen to Bach I feel like I'm putting math inside of me. I've posted the full Suite No. 1 for Cello on the right of this page. See if it doesn't send your mind racing through the periodic table of elements. Or at very least a trip down integer alley.
PS - Mr. Bach deserves a more thorough treatment then this skimpy post. I will likely be adding to it in the next few days when I get a minute.
