The melody of A Little Too Much by Shawn Mendes runs 319 notes across 52 bars, 2:40 long in C at 83 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.
