A♭ Fifth

The A♭ power chord (A♭5) is a quintessential power chord built from the root note (A♭) and its perfect fifth, intentionally excluding the third to achieve a tonally neutral sound. This ambiguous quality allows the A♭5 to function seamlessly over both major and minor chord progressions, making it a go-to choice in rock, metal, and punk music where versatility and power are paramount. When played with distortion, the A♭ power chord produces the thick, saturated tone that defines heavy guitar music, and its straightforward fingering makes it accessible for players building power chord vocabulary. From arena rock to extreme metal, the A♭5 delivers the uncompromising sonic impact that has cemented power chords as a foundational element of modern electric guitar playing. The A♭5 power chord is essential in drop G# tuning (enharmonic to drop A♭), popularized by bands like Gojira and Lamb of God for maximum low-end aggression while maintaining playability, often paired with E♭5, B♭5, and D♭5. Notable examples include Black Sabbath's work in E♭ standard tuning (where A♭5 serves as the IV chord), and Alice in Chains' use of half-step-down tunings where A♭5 provides crucial tonal contrast. Jazz and blues guitarists working in flat keys (like E♭ or A♭ major) also employ this power chord for comping patterns, demonstrating its versatility beyond heavy music contexts, and it's enharmonically equivalent to G♯5.
