The melody of Something To Believe In by Poison runs 442 notes across 61 bars, 6:28 long in Ab at 68 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.
