How to use the F7♭9 chord
The F7♭9 chord is built from a root, a major third, a perfect fifth, a minor seventh and a minor ninth. Start at the root F and stack the intervals to get the whole chord: F, A, C, E♭ and G♭. The same formula gives you the chord in any other key.
Dominant seventh flat nine chords are the classic altered dominant of bebop and gospel, most often the V7 of a ii-V-i in a minor key. Gospel piano voices this chord thick under the vocal line right before it resolves.
How F7♭9 differs from similar chords
F7♭9 is F7 with a minor ninth, a half step above the root, where F9 has a major ninth. Leave out the root and the other four notes form a diminished seventh chord a major third up. That is why it pulls so hard towards a minor chord a fifth below.
Where F7♭9 is used
A dominant chord wants to resolve. Its home is the V of a major key - and the I of a blues, where the pull never lets up.
