The melody of Alone Again (Naturally) by Gilbert O'Sullivan runs 270 notes across 27 bars, 2:50 long in Bb at 65 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.
