If we presume that "Bb7b9" is from phrygian-dominant scale, we would have to presume that it has both major third and perfect fifth, which is a bit unclear from the description of the chord. Phrygian-dominant is the 5th mode of the harmonic minor scale. Harmonic minor scale also features 7 modes (like regular minor scale), and also features 7 chords, build from those modes.
For example A harmonic minor, and the set of 7th chords for it: CODE Chord Notes Formula Am(maj7) A, C, E, G# 1-b3-b-7 Bø B, D, F, A 1-b3-b5-b7 C7(#5) C, E, G#, B 1-3-#5-7 Dm7 D, F, A, C 1-b3-5-b7 E7 E, G#, B, D 1-3-5-b7 F7 F, A, C, E 1-3-5-7 G#o G#, B, D, F 1-b3-b5-bb7 And here's the pattern: If you take a look at the E-F relation, you'll see it's minor 9th interval, which brings us to "b7b9" chord or shortly: E7b9 However, since there is no description for third and fifth, we could easily fit the Bdiminished chord into this category too, since it also features b7b9 notes.

I thought he meant Bb
but yeah that's correct if it's B with a b7 and a b9 -------------------- Visit my:

Yes, I saw the Bb7b9, but it sounded a bit confusing without the third or fifth displayed.

There's no B note in Eb key, here's the pattern (notes are with #, so D# should be Eb here):
B dim is from C major key. -------------------- - Ivan's Video Chat Lesson Notes HERE
