How to play E9b5
E9b5 in 2nd inversion puts Bb in the bass instead of E, the 5th of the chord. The notes are the same; what changes is what the bass line does, which is most of why you would reach for it — it lets the lowest voice move by step where the root would have jumped.

How to use E9b5
E9b5 is a dominant with its tension raised, so it still points at A — harder than a plain seventh does, because the altered tones sit a semitone from where they are going.
Voice by voice, E9b5 → A. 3 voices move by a semitone, and one note is common to both chords.
| In E9b5 | Moves | In A |
|---|---|---|
| E, the root | stays where it is | E, the fifth |
| G#, the major third | rises a semitone | A, the root |
| Bb, the flat fifth | falls a semitone | A, the root |
| D, the flat seventh | falls a semitone | C#, the major third |
| F#, the ninth | falls a whole tone | E, the fifth |
