The melody of Alarm by Anne-Marie runs 438 notes across 93 bars, 3:07 long in C at 142 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.
Prefer to strum and sing it instead? Alarm chords and lyrics.
