The melody of I Believe In You And Me by Whitney Houston runs 363 notes across 50 bars, 2:53 long in C at 80 beats per minute. The tab sits almost entirely in the first two frets, 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.
