The melody of La Sagrada Familia by Alan Parsons Project runs 476 notes across 95 bars, 5:24 long in Cm at 126 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.
Prefer to strum and sing it instead? La Sagrada Familia chords and lyrics.
