The melody of Tessellate by Ellie Goulding runs 282 notes across 74 bars, 3:56 long in C at 130 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.
Prefer to strum and sing it instead? Tessellate chords and lyrics.
