I just googled “Bm7b9 guitar”, and several chord charts came up, I tried it with b9 in parentheses too, and still got results, so I don’t know what’s up with that. But yes, definitely a chord, spelled B D F# A C.

Bm (the notes B D F#) is the Triad, Bm7 adds on the seventh (A) and Bm7(b9) adds an additional extension, the b9.

It’s definitely a chord, but I would recommend though that if you do play the 5th in the chord, you play the flat 5, since it’s in Aminor.

Thanks for the reply. I was able to find the chord after some more searching. I tried playing the flat 5 instead, and it sounds off to me. I'm playing Am9, Bm7(b9), Em7/B. Perhaps I'm wrong about it being in A minor...

when writing chord extensions, often each extension implies the existence of all the previous ones. for example, Bm9 implies that the 7th is also in the chord, and Bm13 implies the 7th and 9th are in the chord. well, its more like they *could* be in the chord. also just because you're not using Bm7b5, it doesn't mean you're not in Am. I mean people often use V7 in minor keys when the 5th should be minor. as long as an Am chord feels like home, and you can play an Am scale over the progression, you're in Am. your progression works becuase there are lots of similar notes between the chords


parentini

That’s helpful, thank you. I guess you would call it a borrowed chord in that case? Just not sure where I’m borrowing it from.

Well all the chords are in G, so if you want it to be Am then it's more A dorian than aeolian. then all the chords are diatonic

Lots of songs work well with non-diatonic chords.
