The melody of One Call Away by Charlie Puth runs 405 notes across 68 bars, 3:05 long in Gb at 92 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.
