Moozart's Symphony No. 35 in D Finale. The only reason I know is because it's on the back of this "Mozart for the Mind" CD my mom made me take. It has a part that reminds me of Vivaldi (whose music I know little about) and I recently just blasted this piece. The part where the violins seem to sway down, then up then down the scale is my favorite. I think it happens twice. That little part is stuck in my head and I don't want to let it go. Can you really get smarter by listening to Mozart? I hope so.
