Re: A weird chord progressionactually, i'm hearing the Bb7#9 in there (the horn punches), as an
upper leading chord down to the Amaj7. check out a mickey baker
chord (13b5b9), as an E13b5b9/Bb, and you will have the tones to the
Bb7#9, which, from the horn players perspective, would be OK, but
theortically would probably make more sense calling it and altered E7
chord, which would progress to the A maj 7 just fine. note that the
chord as mickey shows it to us does NOT have a Root (there IS no E
anywhere- the bass player should be handling that.
the chord would break down like this: as a Bb7#9, the Bb is the
upper leading tone to A (the Flat 9), the D would be the 4th of the
scale, leading to the C# (the 3rd of A) OR E (the 5th of A) , the F
would be the upper leading tone to E, the 5th of A, and the 7th, Ab
(or G#) , would be the lower leading tone to A and ALSO the common
tone G# (the major 7th of A) . the sharp 9th (C#), is a common tone
with the A chord - the 3rd).
as the "Other" Mickey Baker chord (E 13 b 5 b 9 ), the altered E 7
chord simply resolves to A maj 7. and the Bb chord would be a tritone
sub for the E chord. either way, it's one of those things that works
cuz it SOUNDS cool, no matter how you theorize it.
