The melody of Always In My Head by Coldplay runs 109 notes across 30 bars, 2:55 long in Gm at 99 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.
