F9 Piano Chord

F9 is the F dominant ninth chord. It has five notes: F, A, C, E flat and G. The stack is wider than an octave, so most players put F in the left hand and the other four notes in the right.

F at the bottom, then A, C, E♭ and G. Right hand 1-2-3-4-5 if your hand spans a ninth; otherwise F in the left hand and the other four notes in the right.

How to play F9 on piano, step by step

Start on the F above middle C. That is the lowest note of the chord.
Thumb (1): F
Index finger (2): A
Middle finger (3): C
Ring finger (4): E♭
Little finger (5): G
That reach is wider than an octave, so most players split it: play F with the left hand and the other notes with the right. If you keep it in one hand, leave out the fifth (C), the note the chord misses least.

A blues in F is the most played jazz blues there is, and F9 is its home chord. Learn this shape and twelve bars of comping are already under your hands.

If it sounds wrong

The reach is too wide: F to G is a ninth. Split the chord: F alone in the left hand, A, C, E flat and G in the right. That is the standard way to play it.
It sounds soft instead of bluesy: The seventh must be E flat, the black key. E natural turns the chord into Fmaj9, a completely different mood.
Five notes come out uneven: Drop the hand as one shape rather than five separate presses. The ring finger on E flat is the usual weak spot; let the wrist lean slightly toward it.

What makes it an F9

F · A · C · E♭ · G 1 3 5 ♭7 9

F9 is an F7 chord with a G added: F, A, C and E flat make the seventh, and the G a ninth above the root rounds it into F9.

F9 is the V9 of B flat, the seventh chord blues, soul and funk actually play instead of the plain F7. It is also the home chord of a blues in F, the key jazz players run their blues in more than any other.

F9 vs F7

F9 is F7 with a G on top. Both pull toward B flat, and both work as the home chord of a blues in F; the ninth is simply the fuller voicing.

Play F7, then add G with the little finger. In a jazz blues the plain seventh sounds like a sketch; the ninth sounds like the record.

Questions about F9

Which notes are in an F9 chord on piano?

F, A, C, E flat and G. E flat is the only black key, and the G on top is the ninth.

What is the difference between F9 and Fadd9?

The seventh. F9 contains E flat; Fadd9 is the plain F major chord with a G added and no seventh.

Why does this page show no inversions?

A ninth chord is wider than an octave, so lifting the bass note an octave lands it inside the chord rather than on top. Players thin ninths out instead, dropping the root or the fifth.

Can I leave a note out of F9?

Yes. The fifth, C, goes first. With the root covered by a bass player or your left hand, the right hand can play just A, C, E flat and G.

Where is the F9 chord used?

As the V chord of B flat and as the home chord of a blues in F. Jazz, soul and funk piano parts reach for it constantly.
