How it is built
On Gb it is Gb · Db: just 1P · 5P. Omitting the third is the point. With no third the chord has no quality, so it fits over major and minor contexts alike.
How it is used
Distortion multiplies every interval in a chord into sum and difference tones. A third turns to mud under heavy gain; a bare fifth stays clean, which is why rock and metal are built on this shape rather than on full triads.
On guitar it is a two- or three-finger shape that slides unchanged up the neck, since the strings it uses are tuned a fourth apart.

- What notes are in Gb5?
- Gb5 contains Gb · Db. Name any set of notes with the chord identifier.
- Is a power chord major or minor?
- Neither. It has no third, which is what makes it work over both.
- Why do power chords suit distortion?

- The Gb Fifth chord contains the notes Gb · Db: the root Gb with the intervals 1P, 5P stacked above it. Play them together for the chord or one after another for an arpeggio. The lowest note is normally Gb, but any chord tone can take the bass in an inversion.
- What intervals make up the Gb Fifth chord?
- Measured from Gb, the Gb Fifth chord stacks the intervals 1P, 5P. The quality of the third and of the seventh, if there is one, is what gives the chord its character; the rest of the notes colour it. Every interval in the formula links to its own page, with its sound.
