Systems Down

Systems Down by AC/DC is played in the key of A. Arranged in the natural sounding key of A in standard guitar tuning without a capo, 'Systems Down' by AC/DC utilizes direct fretboard shapes to project full open-string acoustic warmth and resonance throughout every section. The song relies exclusively on open cowboy chords (G, D, A5, G5, D5, E5, B5, F5, F#5), letting beginners concentrate on tone clarity, ringing string resonance, and sustain without encountering demanding barre finger fatigue. The primary progression challenge lies in switching between G and D: keep your fingers hovering close to the fretboard rather than flying off between changes. Set your metronome at an initial practice tempo of 66 BPM in 4/4 time to master the '↓ - ↓ ↑ - ↑ ↓ ↑' strumming groove, emphasizing steady downstrokes on beats one and three before accelerating toward the studio speed of 92 BPM.
