Hi!

I'd like to play over the jazz standard BLUE BOSSA but I can't find a way to input a m7b9 chord.

This is not included in BIAB ???

Aren't you wrong? Didn't you mean a chord like Dm7b5?

Ya, Likely a typo.

Dm7b5 to G7 to Cm is common in many fake books for BlueBoss. However the substitution of the G7 with G7b9 is often seen. It is a nice jazzy guitar chord! I suspect that may be what the OP was indicating. In this case BIAB does have all these chords.

BB was in my play set back in the day. grin
I did a cover recording with a fellow named George Bellas who some may recognize as a big time talent. As close as I ever got to the big time. crazy

A m7b5 chord is in BiaB's chord arsenal.

A m7b9 chord is not. Weird?

Dm7b5 is probably the chord they are looking for.

A quick google search for Am7b9 (I picked "A" arbitrarily) shows this:

**************************************************************************************

Am7(b9) Guitar Chord
Am7(b9) Guitar Chord. 4 chord voicings, charts and sounds. Chord notes and structure: A Bb C E Ab (R m2 m3 5 7).

Am7(b9) Chord
Standard name: Am(maj7)b9
AKA: Am(+7)b9; Am(+7)b7/9; Am(maj7)b7/9; Am(+7)b7/9;

***************************************************************************************

Maybe one of the AKA's would work.
Good luck!

Lloyd, I believe your Am7b9 is notated wrong. It should be A Bb C E G

Here is the piano version of Am7b9:

If the A is in the bass wouldn't it be Am7b9?

If the C is in the bass wouldn't it be C7add6.

Same notes different labels!

Either way it works!

I believe it will be a half diminished chord as my learned colleagues suggest, but the mMaj7b9 chord should be a Neapolitan Minor and the sound is very weird and difficult to resolve, so I would steer away from that chord. Nobody plays that scale on standards, maybe Brecker, Branford or Trane...

It could be just the phrygian chord:
the III chord in any major tune and the
V chord in the relative minor.
Mostly it is notated as plain minor or as sus4b9 or as the slash chord F/E, where the triad F is played over E in the bass. I have never seen it notated as mb9, not in the realbooks, not in the New Real Book...
Angelomusic, can you upload the sheet music? There’s a lot of players here who are willing to help out.

Boys, please, there's only 12 notes in a scale, don't mess around with that.
And as Woody Guthry said: More than three chords in a song is showing off anyway.
