The melody of It’s Not For Me To Say by Johnny Mathis runs 186 notes across 37 bars, 3:01 long in Bb at 90 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.
