Mac,
Please explain the term: "from the 9 forward".
I've been around musicians, music instructors, professors, for a long time and have never heard the term. And, it didn't come up in a google search.
I can only try to guess at it's meaning.
Thanks
It is an old term used at one time by the originators of the then new form of jazz improvisation that was developed by Charlie Parker, Dizzy Gillespie and others, eventually coming to be known first as "bebop" but these days could include other genre titles such as Modern Jazz etc.
I just enjoy using older terminologies like this one.
Anyway, what is meant here is the selection of notes, modes, scales, even extensions to the written chords by mentally extrapolating the extension notes that would fall above the highest note or extension of the written fake chord and proceeding to use that for your improvisation.
Likely the beginning example of such would be the common jazz substitution for the dom7 chord where even the comping instruments can elect to play that dom7 as a 9 chord without fear of clashing. Ex: The chart has an F7 as the turnaround chord in key of Bb, but the pianist or guitarist can and often will change that to an F9.
Keep expanding that additional note and we find that the next logical note above the 9 would be the 11 (Bb in this case) and finally the top note we can extrapolate would be the 13, or the D.
Now we have a situation where the chart calls an F7 chord as the turnaround, the chord compers in the ensemble have an elective situation in which they might change that simple F7 to an F9 or maybe even the more dense F11 or F13 and not change the basic harmony happening in the turnaround, well the soloist can use the same theory and way of thinking.
Let's spell that F13 substitute in close harmony for a second, to make this clear:
F,A,C,Eb,G,Bb,D
One way of thinking about this now is that each three successive notes spell a basic triad within this chord.
F-A-C is the simple root Major mode, Inside
A-C-Eb describes an A diminished chord, Inside
C-Eb-G describes a C minor, Outside because "F7" written
Eb-G-Bb describes an Eb Major. Outside
and G-Bb-D describes a G minor, Outside
But wait, it goes deeper.
Can you look at the note stack and readily see the Maj7 hiding in there?
Again, for reference, F,A,C,Eb,G,Bb,D
Eb,G,Bb,D describes the EbMaj7. Bird might then choose to stick an EbMaj7 arpeggio in there somewhere, right? Transcribe and analyze a few Bird solos. Again, it is not an EbMaj7 in "correct" terminology, it is just a way of thinking about it that simplifies what's really going on. KISS kinda thang.
We can extrapolate a mode in which we can solo from any of those triads hiding inside and outside of this chord.
If we choose to use only the parts of the chord that start outside of the octave, which is at the 9, then we are talking about "playing from the 9 forward".
Note that the added extension notes are in reality merely playing the harmonic series, these notes are actually generated anyway when you play a chord with less extension, but since that natural generation of harmonics is always going to be of much less energy or amplitude, which is also dependent upon factors such as instrument timbre, type of sound generator, resonant factors, etc. we don't or cannot actually hear those notes in there.
Just another way to *perceive* the situation.
There are different ways of thinking about it, which, while maybe taking a different *approach* all ways are valid if the end result achieves the same goal, which in this case is addee Tension.
One last thing, "9 forward" also can include the b9 in certain cases (ALT usage comes to mind).
An experiment that I think that *every* aspiring musician/soloist should try is to find a keyboard that is in good tuning and equal temper, and play stacked fifths.
C,G,D,A,E,B,F#,C#,Ab,Eb,Bb,F and back again to C at the top.
Of course, we can't really do that with two hands, but we can play the CGDAEB easily enough and hear what's happening there. Analyze. It'll do ya good. Keep at it and you will find that you can go Lydian in a heartbeat while soloing.
Always bear in mind that these kind of things deal with our *perception* of the theory and there are many different ways to get to the same end result, which is being able to familiarize ourselves with these various sounds so well that someday we get to the point where we can create on the fly rather effortlessly.
Another great - and different - example of perception is the methodology or way of thinking employed by Pat Martino, in which he approaches this in much the same fashion actually, but with fewer rules. For example, when encountering that same turnaround situation as my example, Pat simply jumps up to the fifth of the chord - and plays in the melodic minor mode for the resulting thought-chord. Great for guitar players, the root of the chord is F in this example, Pat would most often grab at the Cm melodic from the Cm scale positions on the neck.
Don't neglect that hidden diminished chord in there, either, here you can often use the diminished scale or the wholetone scale with impunity.
