The melody of I Guess That’s Why They Call It The Blues by Elton John runs 395 notes across 56 bars, 4:39 long in C at 120 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.
