The melody of How Could You Believe Me When I Said I Love You When You Know I’ve Been A Liar All My Life? by Alan Jay Lerner runs 214 notes across 66 bars, 1:15 long in Eb at 252 beats per minute. The tab sits low on the neck, mostly under the fourth fret, 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.
