The melody of 8 Letters by Why Don't We runs 363 notes across 51 bars, 2:39 long in E at 88 beats per minute. The tab sits low on the neck, mostly under the fourth fret, 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.
