The melody of I Choose You by Sara Bareilles runs 366 notes across 98 bars, 2:55 long in A at 152 beats per minute. The tab sits moving up the neck in places, one note at a time — no chords to barre and no strumming pattern to keep up with. A piano backing track plays the chords and bass underneath, so the line you are learning sounds like the record even at half speed.
