Lesson
Three
Turnarounds
Turnarounds
are very important to master in all keys. They happen in the last
two, or four bars of most songs, providing the necessary harmonic
"gravity" to get you back to the top of the chart. They
are also a great way to learn the basic chord substitutions, and voice
leading techniques used in jazz.
Example
One shows the basic turnaround chords in the key of F, also known
as the I-VI-II-V progression.
One of the
first substitutions you will run into is found in Example Two,
where a D7 is used instead of the original Dmi7 chord.
This is known
as the "V of II" chord, or quite simply the VI7 chord. It's
function is to set up the II chord. Changing it to a dominant chord
from the original mi7 helps to create more tension, and a feeling
of resolution once you land on the II chord. As a rule, you can remember
that in jazz, more often than not, the VI chord is treated dominant.

Example
Three is a single-note fine that "cuts" through the
changes quite effectively. Notice the F# in the first bar. This is
the characteristic note of the D7 chord, the only note that will tell
the listener you have used D7 instead of Dmi7, as it is the Ma3rd
of the chord. If we had used F natural, it would have implied a Dmi7
chord. The second bar uses notes from the altered scale over the C7
chord which provide tension until the line resolves to an A, the Ma3rd
of the I chord (FMa7).

Example
Four uses another common chord substitution, an Ami7 instead of
the original FMa7 in the first bar. This is known as the III-VI-II-V
progression, instead of the original I-VI-II-V. Notice that we now
have two consecutive II-V progressions, the first: Ami7-D7, and the
second: Gmi7-C7. In short: III has substituted for I. The single note
line reflects this substitution accurately, beginning with an Ami7
arpeggio (A C E G).
The importance
of turnarounds cannot be overemphasized. Write these lines out in
all keys, practice them in different octaves as well. Jamey Aebersold's
play-along package Turnarounds, Cycles, And II-Vs is an
ideal practice tool which will enable you to play these examples with
a rhythm section.
