Hope everyone's well, anychance someone could shed some light on these chords please


(not the Ab6, I got that one)




(EDIT: ooops I can work this one out using Rossy's earlier post - I think)

Thnx in advanced

Bb9-5 = B Flat Ninth, Diminished Fifth

Bb9= Bb/D/F/Ab/C
Bb9-5= Bb/D/E/Ab/C

You nailed the Bb9. The Bb9-5 would sound right if you played it, but I think maybe it should be written Bb/D/Fb/Ab/C. Fb rather than E, because even though it's diminished you're still referring to a fifth (B to F).

Oh, thnx,

How about the C7-9

To me it reads C dominant 7 diminished 9th (but there isn't a 9th in C dominant 7)?

And the G(with the tiny o) I haven't a clue

The G (tiny o) is diminished so that's G, Bb, Db.

C7-9 means a C7 with a flattened 9. So it will be C, E, G, Bb and Db.

Oh, I'm sorry about that! I was so focused on the one I forgot about the other two, haha. The little circle means diminished. A diminished chord consists of the root, a minor 3rd and a diminished 5th. So in the example above, G diminished, it would be written G/Bb/Db.

On the C7-9, you're right. It's a C dominant 7 with a flatted 9th. So that would be written C/E/G/Bb/Db

Edit: What Andy said... I was a bit too slow.

Do you know how to read guitar chords? That would give you an extra key (no pun intended) for unlocking these notes.

On the G° (G Diminished) chord, which is G, Bb, Db, I'm confused because the chord chart seems to throw in an extra E. What does anyone else think about the first dot on the guitar chord, which I make to add E to the chord?

Bit sloppy really, but I've seen G° used when it really is G° 7; I'm guessing that's what happened here.

You can add an E to a G diminished chord, it makes it a diminished 7th chord. It is the exception to the 7th rule. A fully diminished 7th chord has all minor 3rds (technically, G, Bb, Db, Fb). As opposed to the diminished chord with the traditional minor 7th, called either a half diminished (circle with a slash through it) or more commonly in jazz the minor 7, flat 5 chord (Gm7b5).

However, I doubt it would be voiced at the bottom of the chord like that, so in reality it was probably an editor missing the X on the first string.

Thank you Andy Platt! Now I see. G Fully Diminished 7, so G, B, Db, Fb.
