The melody of Wolves by Selena Gomez & Marshmello runs 507 notes across 59 bars, 3:18 long in Bm at 122 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.
Prefer to strum and sing it instead? Wolves chords and lyrics.
