The Jazz Player's Handbook
Extensions and Alterations
Rule 1:

A jazz player never uses a plain major chord or a plain dominant 7th except for effect.

A C Major chord can become: C6, C Major 7, C Major 6 add 9, C Major 9, C Major 7 b5, C Major 7 aug. 11, C Major add. 13, C Major 7 #5, C Major 7 add. 6 add. 9, C Major 9 b5, C Major 9 #11, C Major 7 #9 #11, C Major 7 b5 b9, etc.

A C Minor chord can become: Cm6, Cm add. (major 7), Cm add. 9, Cm (add. major 7 add. 9), Cm b5, Cm (major 7) b5, Cm #11 (add. major 7), Cm6 (add. major 7), Cm#5, Cm6 add. 9, etc.

The C Dominant chords become: C9, C11, C13, C7b9, C7#9, C7b5, C7#5, C7#5b9, C7b5#9, C7#5#9, C7b5b9, C9b5, C9+11, C13 add. 11, C13b9, C13#9, C7sus.4, C9sus.4, C13b5, C+7, C+7b9, C+7add.9, C+7#9, etc.

Substitutions
Rule 1:

Diminished chords become 7thb9 chords by using them over a root a half-tone lower than any note in the chord. Each diminished chord provides four 7thb9 chords. Taste will decide the choice.

Example: C diminished chord (º)
Rule 1

The Major scale is harmonized in four note chords. For purposes of substituting and transposing, that harmonized scale should be memorized by chord names and numbers.

Example: Key of C Major - Transpose to all keys.
Rule 1 continued

Rule 2:

(3) minor 7th chords and (6) minor 7th chords = the (1) Major chord.

Example: Em7 + Am7 = CMajor7

Rule 3:

The 5 minor 7th of a dominant 7th chord can be used before, after or in place of the dominant 7th chord

Example:
Rule 3
Rule 4:

When the (2) minor 7th chord is placed before the (5) dominant 7th chord, a 2-5 chord progression is created.

Example:
Rule 4
Bass line moves in 4th's - (D-G-C)

Rule 5:

When C four beats and G7 four beats is found, combining rules 3 and 4 will give you the very very common 1, 6, 2, 5 progression.

Example:
Rule 5
A variation on this is the 1, 3, 2, 5.

Example:
Rule 5 continued
Rule 6:

The flat (5) dominant 7 chord of the dominant 7th chord can be used in place of the 5 dominant 7th.

Example:
Rule 6
Rule 6 continued
add a flat to create the Db9
flat 5 of 5
Db9    to    CMajor7

Db dominant is the flat 5 substitute of G dominant. This is also called the tri tone sub-the tri tone being achieved by counting up 3 whole tones from the root-
Rule 6 continued      Rule 6 continued

Bass line moves chromatically   (D-Db-C)

Rule 7:

A minor 6th chord leading to a dominant 7th chord one whole root tone above (Gm6 to A7b9) is misspelled. It should be (5) minor 7thb5 of the dominant 7.

Example: (Gm6 to A7b9) should be Em7b
5 to A7b9.
Gm6 and Em7b5 have the same notes but different root.

Rule 8:

When leading to a minor type chord, always alter the dominant 7th before it.

Example: (G9 to Cm)
G7b9 to Cm, G7#9 to Cm, G+7(G7#5) to Cm etc.

Remember to combine rules. Always play all of your choices, then decide on the ones you like. Keep the melody in mind and use your ear!

Remember that any chord with a flat 7 in it is a leading chord and any chord with a major 7 (natural 7) stops the harmony. The (2) M7 or (5) dominant 7th determine your tonal centers. They both lead to 1 which is your tonal center.

Example: Dm7, G13 bring you to C Major (C minor).

Many chords have the same notes and become different when used with different bass notes or placed in progressions in different ways.

Example:
G6 and Em7 are the same chord.
GMajor9 and Bm7 are the same chord.
Gm6 can be C9, Em7b5, Gb+7b9, Bb6b5, Db9, can be Eb9 sus.

A minor 11 (no 3rd) can be used for D11 or D sus.
C7b5 can be used for C7+11 or Gb7+11.
Gmin.9 = Bbmaj.7.
Gm maj.7 = Gb+, D+, B+
Gm6 = C9, Em7b5 etc.

These are but a few examples. Try to find more. They are useful for improvising.

The difference is in what the chord is moving to, or what is being used in the bass.

Minor third intervals also play an important role in substituting.

Example: C7, Eb7, Gb7, A7 can all lead to F major.

Rule 9:
Dom. 7th chords a minor 3rd apart sub for each other. The same holds true for minor 7th chords.

Example: Gm7, Bbm7, Dbm7, Em7 all can lead to F. Also Major 7th chords can move in minor 3rds.

Example: Gm7 leads to Fmajor7, Abmajor7, Bmajor7, Dmajor7.

Try 7thb9 chords in minor 3rds and listen. You'll soon find out what sounds good. Play dominant chords in the cycle of 4ths. Then play 2 - 5 progressions in the cycle. Use major 7ths in place of some or all of the dominant 7ths in the cycle of 4ths for resolutions, etc.

Rule 10:

At times the (4) major 7 or (4) dominant can be used for the one chord.

Example: Fmajor7 or F9 in place of Cmajor7.

Rule 11:

At times a minor 7th can be made into a dominant 7th using the same root. For thorough knowledge, everything should be practiced in the cycle of 4ths. It'll take a while, but it will certainly be worth it. There should be no favorite key. They're all musical and should be used as such.

All of these rules apply to the scales and arpeggios for improvising as well as chord playing.


What can be played over different chords?

One of the most frequently asked questions in the study of jazz improvising is, "What can be played over a given chord or progression?" The following examples should clear up some of the mystery concerning this aspect of playing, but first a few general comments are in order.

While it is important to have a thorough knowledge of the different scales, arpeggios, chords, etc., which make up the music, you must remember that jazz is like a language and, as such, it has its unique vocabulary, cliches, nuances, and subtleties. To communicate on common ground with other musicians, you need to be familiar with these things, as well.

Listening to and playing along with records is one of the best ways to learn conception and time feeling. Become aware of the ways different players interpret similar chords and progressions. Many guitarists tend to listen almost exclusively to other guitarists (this is probably true of other instrumentalists, as well). While there are many fine guitarists from whom much can be learned, you are placing serious limitations on yourself by not listening to other musicians, as well. Charlie Christian was heavily influenced by the playing of saxophonist Lester Young, while many of the more recent guitarists claim to have been influenced greatly by musicians such as Charlie Parker, John Coltrane, Wayne Shorter, and others.

Listening to some of the great pianists, such as Herbie Hancock, Bill Evans, Wynton Kelly, Tommy Flanagan, Chick Corea, Horace Silver, etc., will help you develop a feel for time, comping, and overall rhythm-section playing. Listening to some of the great rhythm sections (Count Basie, Miles Davis, Art Blakey, et al) will also help.

The following pages list some chords and progressions which are common to the jazz repertoire, along with some of the possibilities (scales, devices, etc.) that may be used to solo over them. Bear in mind, however, that these are by no means the only ideas that may be used, and it is strongly suggested that you also experiment on your own.

Remember, too, that even though a chord or progression is shown in one key, the same rules apply to all keys. If, for example, an F mixolydian mode is suggested for an F suspended chord, a C mixolydian would be used for a C suspended, and so forth. Consult the scale syllabus at the front of this book for any scales with which you may be unfamiliar.

  • Dm7 - D Dorian or D Minor Pentatonic
  • G7 - G Mixolydian, G Half Tone-Whole Tone or any of the scales shown in this section for dominant chords (altered and non-altered)
  • D Dorian or G Mixolydian will cover the whole progression

////       ////
  • D Harmonic Minor will cover the whole progression
  • Em7b5 - E Locrian, E Altered Dominant, E Dorian b2b5, E Aeolian I 5, or E Altered
  • A7alt - A Half Tone-Whole Tone or A Altered
The following cycle progression is used in many jazz standards, most notably as the bridge chords in "rhythm changes."
Cycle Progression
  • D7 - D Mixolydian, A Dorian, D Half Tone-Whole Tone, or any of the scales shown in this section for dominant chords
  • Simply transpose these scales to cover the remaining chords in the progression.
  • A particularly interesting device is to use whole-tone scales ascending or descending chromatically for each chord.
    For example:
    D7 = D Whole Tone
    G7 = Hb Whole Tone
    C7 = E Whole Tone
    F7 = F Whole Tone
Note that the whole-tone scales ascend chromatically to cover each chord. They may also descend chromatically, as in the following example:
D7 = D Whole Tone
G7 = Db Whole Tone
C7 = C Whole Tone
F7 = B Whole Tone
D9 - C9
  • D9 - D Mixolydian
  • C9 - C Mixolydian
  • D Whole tone or G Jazz Melodic will cover the whole progression

G - F
  • G Mixolydian or F Lydian will cover the whole progression

C - Db - Eb - Db - C
  • C Spanish Phrygian will cover the whole progression
Apart from playing scales over every chord change, you may also use the arpeggio of the chord. This is especially useful in situations where the chords are of short duration (one or two beats each, for example). The use of arpeggios also helps to outline the harmony more clearly.

Blue notes (b3, b5, and b 7 of the key) may be used against most chords. As with any musical device, they should be used with discretion and taste.
