The melody of Be Thou My Vision by Eden's Bridge runs 250 notes across 80 bars, 3:33 long in C at 88 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.
