Post by j***@gmail.comWhen you see chord symbols in a lead sheet/sheet music do they refer
to the overall harmony including the melody or what the main
accompaniment instrument is playing or what?
Your question above is not very precise so I don't really understand
exactly what it is that you're asking.
Chord symbols are a type of shorthand musical notation from which a
musician, experienced with chord symbol notation, can improvise a
harmonic accompaniment to a given melody.
They can also serve as the basis for melodic improvisation based upon
the given chord symbols.
In jazz, the chord symbols on a chart are merely a jumping off point and
are not really taken wholly literally.
I.e. A jazz musician may add/or omit notes that are implied by a chord
symbol and may also choose to slightly reharmonize the given chord(s)
based on his own tastes and experiences.
In a jazz combo there is usually only one guy playing chords while
another guy is playing or improvising single-note melodies, so there is
much harmonic freedom - and harmonic excursions away from the written
chart are frequent.
In certain types of other settings (eg. a studio pop chart or a big
band) the chord symbols are taken more literally because if they are not
taken literally the potential for harmonic or melodic clashes with the
other instruments in the ensemble is too great.
Still, even in settings like this the player gets to choose his own
voicings of the chords as well as other aspects of the part that he is
improvising.
If a writer needs a specific voicing from his players then he needs to
write it out in standard notation because chord symbol notation does not
contain that type of information.
Post by j***@gmail.comMany times it seems that
the guitar just doesn't sound good playing many of those chords.
Then either it's a bad chart, or you're playing the chords wrong, or
you've chosen a chord voicing that is not optimal for the passage.
Post by j***@gmail.comIf there is a C13b9#9 does it mean that some instruments are playing
some of the notes and other are playing other notes so that's the
overall sound?
That chord symbol might be actualized across an ensemble the way you
describe, yes.
On a 6-string guitar, the 7-note chord specified by that chord symbol is
impossible to play.
So guitar players learn about which notes they can safely omit from a
chord and which notes are more essential for the sound of the chord.
But a piano player has no problem playing that entire chord.
Post by j***@gmail.comFor example: Guitar = Db F G, Piano = Eb A G , Bass = C
Bb, Vocals = E.
Evidently you don't fully understand what the chord symbols you're
reading are trying to tell you.
This might be why when you play from chord symbols it doesn't sound right.
C13b9#9 [aka C7(b9,#9,13)] consists of the notes:
C E G Bb Db Eb A
There is no F in this chord. The note F will destroy the essential sound
of C7.
It's fairly universal practice in jazz to omit the 5th from any chord
type that contains a P5th interval and it's quite common to omit the
5ths from chords with altered 5ths as well.
That shortens our basic C7 pitch collection to:
C E Bb
1 3 b7
Or
C Bb E
1 b7 3.
1 3 7 and 1 7 3 voicings of 7th chords are known as "shell voicings".
A shell voicing is the bare minimum a player needs to get the sound of a
7th chord into his listener's ear.
Anything else is just decoration or colour.
Most jazz players, working in a small combo, would prefer to see the
chord symbol C7 rather than C13b9#9 - and then they can decide for
themselves what extensions, if any, they will add to the chord based on
the musical context at that point in time.
But in a big band, the larger chord symbol might be telling you that the
other guys in the band are playing a Db an Eb and an A.
The chordal player can then decide to include those notes in his voicing
which, if done sensitively, will support the overall sound across the
entire band.
But more importantly, it tells the player to *not* include any maj 9ths
in his voicing because that will clash with the b9 and the #9 that the
horns are playing, and it tells him *not* to include a b13 in his
voicing because that will clash with the maj 13th elsewhere in the band.
Post by j***@gmail.comI'm confused if I should play the complete chord, as much as possible
on guitar, or if even just one or two notes out of the chord will
suffice even if that changes the overall harmony a bit. Say from a
C13b9#9 to a C7#9.
If you're playing with a bass player, he'll usually be playing or
implying the root, so you can often omit it as well as the 5th.
That leaves you with 3 7 and/or 7 3 voicings as the basic shell of your
7th chords.
The most common way to voice extensions within a 7th chord is above the
main body of the chord.
With C13b9#9, any or all of the following voicings may be suitable for
the needs of whatever passage you are playing;
E Bb
Bb E
E Bb Db
E Bb Eb
E Bb A
E Bb Db Eb
E Bb Db A
E Bb Db Eb A
E Bb Eb A Db
E Bb A Db Eb
etc.
Bb E Db
Bb E Eb
Bb E A
Bb E Db Eb
Bb E Db A
Bb E Db Eb A
Bb E Eb A Db
Bb E A Db Eb
etc.
Note: Even with the omitted root and 5th, not all of those voicings will
be possible on guitar. But most of them will be possible.
Now, extensions don't have to be voiced above the shell.
They can also be voiced in between the 3rd and the 7th.
Egs:
E Db Bb
E Eb Bb
Bb A E
Etc., etc.
