The melody of Thnks Fr Th Mmrs by Fall Out Boy runs 396 notes across 96 bars, 2:44 long in Bm at 155 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.
