F#9 — dominant ninth

Also written Gb9 — the same chord, spelled the other way.

Notes in F#9: F# – A# – C# – E – G#Formula: 1 – 3 – 5 – b7 – 9

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 9 is the dominant chord with the ninth. It keeps the dominant function and adds color and breadth.
