Learn the F 9 Guitar Chord: Theory and Application
F9 is the F dominant ninth chord: F, A, C, Eb and G. The G is the ninth, the Eb is the flat seventh and the A the major third.
The page offers six voicings. One uses an open string, three need a barre, and all start at the 1st fret or above. Seen from Bb major, F9 has the V role, which is why it tends to resolve there. Blends like this appear in jazz chord progressions, with the F Mixolydian scale covering all five notes.
Use the strum and arpeggio playback at the top to listen to how the ninth colours the sound.
F dominant 9th guitar chord is also written as F9, Fdom9, F7(9) or F7add9.
