I'm working on cleaning up a chart I recently got, and aomng the
chords is "A +7 -9". Any idea what might be meant by this? The chart
consistently uses "-" for "flat" and "+" for sharp, but ... "#7"???
I've never seen a sharp 7 chord. Might it be an A7(#9)?
Then notes in the chord (as voiced in the horn parts, concert pitch) are:
F, B, Eb, G, Bb (bottom to top).
I've enjoyed this thread, but it reminds me of why I am not and never
will be a music theorist!! Nor am I likely to play one on TV!
Carl, you spelled the horn parts, but not the bass note, which is a
pretty important piece of information! If there's an A or a C# in the
bass line, it could be some kind of A chord with extensions. But given
just the notes you spelled, and in the absence of a C# or anything that
could be interpreted as a sus3, it ain't no kind of A chord no way!!
The chart is in the key of Bb, and all of the rhythm parts are just
chord changes - no spelled out parts in bass, piano, or guitar (the drum
part there is ////).
The first 8 bar's changes (as written) are:
Eb Eo Bb7 Ab7-9 G+7+9 C9 F7-9 Bb13 A+7-9 Ab7 G7-9
//// //// /// / //// //// // // // // // //
This leaves me thinking that measures 4 and 7 might be Aug7(#9) and
Aug7(b9) chords, but...
This, by the way, is exactly why I discourage the use of plus and minus
signs. Given the spelling with an F, some kind of Aaug5 is obviously
intended, and the plus is intended to be a dagger, but that's exactly
why it's confusing because the plus could have more than one meaning.
My first reaction was that the plus indicated a major 7th. It doesn't!
Tell me about it! The use of the # and b signs make things easier to
understand, as does putting extensions within (parentheses). I don't
know about you, but I'd prefer seeing:
Eb Eo Bb7 Ab7(b9) G +7(#9) C9 F7(b9) Bb13 A +7(b9) Ab7 G7(b9)
//// //// /// / //// //// // // // // // //
any night. It's enough of a change to help with clarity, even if it
does take up a bit more space.
I think I understand Hiro's reasoning, about implying a scale, but since
I'm not a jazzer I do not grok the fullness.
I hear ya.
