The melody of (Everything I Do) I Do It For You by Bryan Adams runs 291 notes across 38 bars, 4:29 long in Gb at 66 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.
