Chord & Fret

A#5 — power chord

Also written Bb5 — the same chord, spelled the other way.

Notes in A#5: A# – E#Formula: 1 – 5

In the formula, the numbers count steps of the major scale starting from the note that names the chord; "b" lowers a half step, "#" raises one — and a slash names the bass note.

The power chord has only the root and the fifth, with no third. Without the third it is neither major nor minor — a neutral, strong sound that takes distortion well.

Where to use it: Rock, riffs and textures where the third would get in the way of the low-end weight.
