Post by funkifizedAnyone work through this book? It's mainly Bergonzi's take on the Bebop scale, with tunes derivative of Bebop tunes such as Blues For Alice, Joy Spring, etc. For minor key tunes, he uses IV7b9b13. Any idea as to why he prefers this to an altered dominant? No lowered 5th or raised 11th? Apparently he's preferring The Harmonic Minor scale?
For example, he's got Cm69 Bebop scale, leading to F7b9b13. Why?
As a writer, he's free to use any colour he wants for a IV chord.
But I don't understand.
Does he use F7b9b13 on several progressions that are in C minor?
Are these all minor blues progressions?
You mention Blues For Alice and Joy Spring.
Are these all contrafacts on the changes of standard tunes?
If so, which minor key tunes are we talking about?
Titles please.
Could this just be a typo for G7b9b13?
As far as usage of the altered dominant chord symbol and the altered
dominant scale is concerned, it's a bit of a pet peeve of mine.
Most jazz educators seem to teaching the altered scale as the default
scale of choice on dom7b9 chords these days.
But that's not the way I learned it or the way I hear it.
In my experience, most times that a writer writes the X7alt chord
symbol, what he/she really want to hear is just a dom7#9#5 chord and
somebody else in the band is often given the P5th or the maj 13th of the
chord to play.
Many times that the X7alt chord symbol is used, the #11/b5 of the alt
scale, if emphasized, just sounds like ass.
So, what that chord symbol was supposed to mean was that it was a shell
voicing of a dom7 chord (1 3 b7)
and
IF the player was going to add a 5th to the chord it would be an altered
5th (b5 or #5), never the P5th
and
IF the player was going to add a 9th it would be b9 or #9, never the maj 9th
and
IF the player was going to add an 11th to the chord it would be a #11
(aka b5), never the P11.
and
IF the player was going to add 13th to the chord it would be a b13 (aka
#5), never a maj 13th.
But many, probably most, writers don't use it that way.
And most of the time the chord-scale relationship that best fits these
chords is what they called "the b9 scale" at Berklee.
It's basically an 8-note version of the 5th mode of harmonic minor.
So, for G7b9, it would be:
G Ab Bb C D Eb F |G
Essentially it just adds a #9 to the 7-note scale (G Ab B C D Eb F |G)
so it has both the b9 and the #9.
It's called "the b9 scale" because it's the scale most closely related
to a dom7b9 chord, especially as V7 in a minor key.
It can also be seen as a mode of one of the bebop scales:
Eb F G Ab Bb B C D |Eb
Barry Harris calls that one, the Eb6 dim scale, I believe.
