Post by thomasPost by Scott DaughtreyPost by thomasLet me restate this--in jazz fakebooks, the chord symbol supercedes
the melody. It is far more important. In many jazz compositions,
the melody is derived from the harmony.
Not a fair statement (and not realistic either). The day this is true we will
"re-melodicize" a harmonic progression instead of the other way around.
Yes, that is exactly how most bebop heads were composed--by writing
a new melody to a common chord progression. Many jazz composers
procede by this method.
And many composers do not. You're absolutely correct, most be-bop heads
(melodies, for those less in the loop) were/are written over common
progressions - however that doesn't mean they were derived from the harmony,
simply that it was the appropriate background setting for the melody. A
composer may easily hear a melody, one which can easily be later supported
thru common form, while the harmony remains in the background and isn't
considered till much later. When you constantly play/compose over a limited
framework it isn't surprising that the imagination when creating melodies is
subconsciously bound to an extent, we only have to look at greats like Bach
and Beethoven to see that they didn't have the freedom of imagination to
create or appreciate more modern compositional tools.
Be-bop is only a piece of what is jazz. Some melodies are derived from
harmonies. But many composers think melodically first, others may work in
combination, hearing bits of a piece with both harmony and melody
simultaneously.
The fact that many players reharmonize on the fly, essentially making the
chord symbols moot, also illustrates that the chord symbol does not supercede
the melody but rather that it must work in tandem. Knowledge of the melody and
how it specifically relates to the harmony is the foundation by which other
players can appreciate and follow another musicians' re-harmonization without
it being written (along with a strong understanding of jazz harmony and
substitutions among other things).
Post by thomasEven when playing standards that were composed by harmonizing a melody,
once the melody has been stated, it becomes secondary to the harmony
for most jazz players. Modern jazz musicians usually pay much more
attention to improvising on the harmonic form than on the melody.
That's debatable as well, it depends on the approach of the improvisor.
Working around the melody and alluding to it is still a common practice, and
not just in be-bop which, yes, typically followed more predicatable harmonic
structures). Secondly, the fact that the harmonic structure becomes the focus
during improvisation has no relevance to the beginnings and inspiration for a
melody nor the choice of harmonic structure
It is all to easy for novice improvisors to get lost in the sea of harmonic
choices available using all the modern harmonic tools, easy to focus on "what
scales can I play over this section of the progression" and "how can I go more
outside, sound cool, impress my girlfriend, terrify my enemies, and resolve it
smoothly". Many mature jazz improvisors still work strongly with and around
the melody, it's one of the elements that seperates the players who see the
progression as a showcase to solo over and the ones that see a musical
opportunity to further enhance the piece. Not passing judgement, just
illustrating the various viewpoints players can have.
Post by thomasPost by Scott DaughtreyAnother example - many jazz tunes share the identical harmonic progresssion,
such as the old worn rhythm changes (yeah, we got rhythm). Clearly it is the
melodic content that seperates one piece from another.
That is rather irrelevant to the question of chord symbol derivation
and use. But it does demonstrate the primacy of harmony in jazz practice.
Woah, hold on here, chord symbol derivation wasn't part of what I was
addressing here (I snipped that part) you were insinuation the importance of
the chord symbol over the melody, a point I still don't agree with. In fact,
Post by thomasPost by Scott DaughtreyWe are not talking on how these symbols are _derived_, but on how they
are to be _interprted_
But since you want to bring it up, fine then, let's tie it in to what you've
Post by thomasYes, it is common to give the bass notes in a fake book. Typically
you will see the chord symbol, followed by a slash and the bass note.
If there is no bass note given, the bassist can assume the freedom
to interpret the harmony his own way.
OK, so let's take a simple beginner's piece like Autumn Leaves, one whose
harmonic structure is a straightforward study. A cycle of fourths, key of
Gmaj/E minor (B flat maj in some books). In the second section we are given a
chord progression: Em7 Eb7 Dm7 Db7 C maj7. In reality, the actual harmonic
progression serves a very specific purpose, an simple extended II-V
(II-V-II-V-I). The actual function of the harmonic progression is much more
accurately described as Em7 A7 Dm7 G7 Cmaj7. The progression has been
"misnamed", for all intents and purposes, to illustrate a figured bass line so
that it descends chromatically and is _not_ interpreted freely as you
suggested.
There's an example of chord derivation, one that is specifially _derived_ from
the intended harmonic structure and written in a specific manner to be used
for _interpretation_, which relates specifically to how the bass should move
thru a common harmonic form. And it uses no slash chords either.
If not for beaing a deliberate pointer to the bass line, the chords would not
be named as they were. An experienced improvisor, or anyone familiar with
basic jazz form, would not see the written progression as Em7 Eb7 Dm Db7 Cmaj7
either, they would see a II-Valt. followed by a II-Valt.-I, a much more
reasonable and substantive form to play thru/over.
So, yes, sometimes slash chords make the "obvious" statement of a specific
bassline however even standard chords often paint out specific bass lines to
the trained eye (well, it shouldn't take much of a trained eye to see the
chromatic movement in the bassline indicated in the harmonic progession of
Autumn Leaves I cited!).
Post by thomasPost by Scott DaughtreyAre you in the habit of mistaking Donna Lee for I Got Rhythm? I seriously hope
not.
Those are two radically different chord progressions. I don't
get the point you're trying to make with this example. Why
would I confuse Indiana changes with Rhythm changes?
I just confused two Parker titles, no biggie. I likely don't need to name a
Parker piece that uses rhythm changes for you, do I? I bet not. The point,
however, is if two pieces share the same harmonic progression then therefore
the melody is what instantly seperates them. To say the melody is subordinate
to the harmony is a matter of perspective considering the melody is the only
aspect that differentiates between them; some would say without the melody the
harmonic progression would be useless, it could be one of a thousand pieces,
and that a good melody can be played with no harmony - the harmony will be
implied (just as in a good solo). Which leads which (?) - chicken or egg
argument. As you say, in some styles it is more prevalent for "form" and
associated harmonic expectation to lead the melody, but that is a gross
overstatement where the field of jazz is concerned just as it would be in
classical music. Sometimes it takes hard work to fit the form around a melody;
it would likely be a much easier task if the melody was simply derived from
the harmony.
