The melody of As Time Goes By by Rod Stewart runs 343 notes across 49 bars, 4:00 long in Bb at 74 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.
