Chord and Fret

G(b5) — major flat five

Notes in G(b5): G – B – DbFormula: 1 – 3 – b5

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.

It keeps the major third and lowers only the fifth by a semitone. It is the major triad seen through cracked glass: still recognisable, but something is out of true.

Where to use it: A rare, modern colour; in practice it shows up far more with the seventh attached, as C7(b5), than on its own.

Every region of the neck hides more shapes of G(b5). In Chord and Fret, you hear every shape strummed string by string, in each instrument's own voice; compare positions with their difficulty marked; and change the tuning — the shape rewrites itself.
