STEP ONE: Find some headphones. Good ones.
STEP TWO: Sit down somewhere quiet where you won't be distracted.
STEP THREE: Listen to this.
Awesome, no? That's Bach's arrangement of the first movement of Vivaldi's Violin Concerto No. 9 In D Major (RV 230), which is pretty awesome in its own right (as you can see/hear HERE). Or you can listen to a harpsichord version or a guitar setting or the piano.
Or you can watch Dan Nesbitt's video, which is what made me think about it in the first place.
