Pentatonic Scales
In addition to major and minor scales, folk, jazz, and popular musicians typically employ penta-
tonic and blues scales. For an example, look at the melody for “Amazing Grace,” shown in Exam-
ple 12.1. In this melody, there are only five scale degrees, 1^, ^2, ^3, 5^, and 6^ in G major. This is a major
pentatonic scale. Since 4^ and 7^ are missing, there is no 7^–1^ or 4^–3^ half-step motion. Melodies
based on the major pentatonic scale typically are harmonized with chords from the major scale.

Listen to Example 12.2, “Wayfaring Stranger,” another pentatonic melody. From the key sig-
nature, the sound of the melody, and the beginning and ending notes, you might guess that the
tune is in D minor, but the melody includes only five notes of the D natural minor scale: 1^, b ^3, 4^,
5^, and b 7^. This scale is known as the minor pentatonic. Melodies based on the minor pentatonic
scale are often harmonized with chords from the natural minor scale. These are not the only
possible pentatonic (five note) scales; other pentatonic scale types are heard in non-Western
musics.

Example 12.3 compares the major and minor pentatonic scales beginning on C: both share C
and G (1^ and 5^), and each has the quality of the third associated with its name, major or minor.

Like relative major and minor keys, there are major and minor pentatonic scales that share
the same pitches, but have different tonic notes, as shown in Example 12.4. One easy way to
remember the pattern of the pentatonic scales is to think of the black keys on a piano. Play the
black keys from F # to F # (or G b to G b ) as shown in Example 12.4 to make a major pentatonic
scale with F # as tonic. Then play the same collection of black keys from D # to D # (or E b to E b ) to
make a minor pentatonic scale with D # as tonic.

KEY CONCEPT The blues scale shares most of its pitches with the minor pentatonic,
with an added # 4^/ b 5^. A performance of a blues melody with accompaniment blurs the
distinction between major and minor by including both ^3 and b ^3 and both 7^ and b 7^.

The anthology includes two scores for “Blues for Norton”: one is a full score that shows what
each instrumentalist plays on the recording (p. 400); more often, blues performers play from a
lead sheet (p. 399), which gives the primary melody plus chord symbols. Instrumentalists im-
provise their parts from these musical cues. Follow the lead sheet as you listen to the recording.
The piano part, not included in the lead sheet, is created by the pianist on the spot, following
the chord symbols. Likewise, the bass player not only supplies the roots of the chords, but also
adds considerable melodic and rhythmic interest to the performance with improvised stepwise
motion and some arpeggiations of harmonies.
Example 12.7 gives the lead sheet for the first twelve bars of “Splanky.” Listen while follow-
ing the lead sheet. (The performance also includes a long piano introduction not shown here.)
Compare the pitches of Example 12.7 with the blues scale shown in Example 12.6.

Basie’s melody draws on the full blues scale on C except for B b (which, however, is present in the
C7 chord, C–E–G–B b ). The F # ( # 4^) in the ascending melody in measure 3 becomes a G b ( b 5^)
in measure 4 when the melody descends. The notes E n and E b (3^ and b ^3) are heard simultane-
ously, as is typical: the melody in measure 1 features the blue note E b , while the C7 chord har-
monizing it has E n. Although the blues scale is based on the minor pentatonic scale, it is typically
harmonized by chords from a major key. In “Splanky,” the key signature provided is for C major,
but the melody is based on the C minor pentatonic scale, necessitating many accidentals. This
juxtaposition of major-key harmonies with the minor pentatonic scale in the solo parts accounts
for much of the distinctive character of blues compositions.

ASSIGNMENT 12.1
Another important aspect of blues style is its harmonic structure. Unlike a 32-bar song form,
with four 8-measure phrases, the 12-bar blues consists of a single harmonic progression or set
of chord changes (called the changes by jazz musicians) that is repeated many times over the
course of a performance. It is helpful to think of the progression as three 4-bar units, labeled
(a), (b), and (c) in Figure 12.1. The progression begins with 4 measures of tonic harmony (a),
followed by 2 measures of IV and 2 measures of I (b). The last 4 measures (c) feature the chords
V–IV–I and end with a final tonic measure. This last measure may serve as a turnaround, with V
or V 7 instead of or after the tonic, leading back to the beginning (a) for another repetition of the
chorus. Each harmony may be played as a triad or dominant seventh chord, as shown.
(a) I (7)
(turnaround)
In popular styles such as jazz and the blues, harmonic progressions and dissonance are
treated differently from their counterparts in classical styles. First, the seventh chord is con-
sidered as stable as the triad. Seventh chords may appear on any degree of the scale and on
nearly every change of chord. Second, while in classical music chordal sevenths are considered
a dissonance that must resolve down by stepwise motion, in popular styles sevenths may be
left unresolved for their color or dramatic effect. Third, the progression V–IV (or V 7–IV 7) is an
integral part of the 12-bar blues (occurring at its final cadence) and is standard practice in rock,
but it is rare in classical compositions and folk songs.
Example 12.8 shows the blues chord progression for “Splanky” in lead-sheet notation, with-
out the melody. The four slashes in each measure mean that performers should improvise on
F7 C7
G7 F7 C7
Listen again to “Splanky,” following the chord changes; it may help to sing the chord roots along
with the recording. Try out its progression at the keyboard (you can simply play the chord once
per measure, or repeat it on each beat), then play through Basie’s melody or create your own,
drawing on the C blues scale from Example 12.6. In blues practice, players first perform the ini-
tial tune and progression (together called the head), then with each successive chorus, various
performers improvise over the chord changes. The head usually returns at the end of the perfor-
mance, and sometimes in the middle as well. The 12-bar blues progression was adopted by rock
musicians in the 1950s and appears in songs of many styles after that time.
Seventh Chords
Seventh chords, pervasive in popular styles, may be built on every degree of the scale, resulting
in many different types of sonorities.
KEY CONCEPT Seventh chords consist of four tones: a root, third, fifth, and seventh
(see Chapter 9). A seventh chords is named for the quality of its triad plus the quality of
its seventh.
Example 12.9 illustrates the five most common seventh-chord types, with an example of
each built above middle C. A major-major seventh chord (MM7) is a major triad plus a M7; a
minor-minor seventh chord (mm7) is a minor triad plus a m7. A MM7 is often called a major
seventh for short, a mm7 is a minor seventh, and a major-minor seventh chord (Mm7) is a
dominant seventh. A seventh chord built from a diminished triad and minor seventh (dm7)
is typically called a half-diminished seventh, abbreviated Ø7, and a chord built from a dimin-
ished triad and a diminished seventh (dd7) is a fully diminished seventh (or just a diminished
seventh), abbreviated º7.

The bottom rows of Examples 12.10 and 12.11 give the chord symbol for each seventh chord.
Write augmented triads with the root plus an indication of the raised fifth, G( # 5), or with a small
plus sign (G+). Diminished triads are indicated by Gdim or Gº. Some lead sheets notate dimin-
ished triads as a minor chord with a lowered fifth: Gmin( b 5). Although seventh chords appear
frequently in popular music, the labels used to designate them are not completely standardized.
Alternate labels for seventh chords above C are listed in Figure 12.2.

The chords indicated in measure 29 begin with Eb, then change to Eb6, a chord with all the pitches
of an E b major triad, plus a major sixth (C) above the root. Pitches added to triads or seventh
chords are sometimes called chord extensions. This particular sonority is an added-sixth chord.
There are other added-sixth chords in measures 33 and 35–36. The added sixth is generally a
major sixth, whether the triad to which it is added is major or minor. Write the chord symbol
with the name of its root (and quality) plus the label 6 or (add6). If you see C6 or Cadd6, write
a C major triad plus a M6 (A); if you see Cm6 or Cmin(add6), write a C minor triad plus a M6.
Look at Example 12.14 for another type of chord extension: the ninth chord. In measure 22,
the F9 chord consists of an F dominant seventh chord (F–A n–C–E b, the third and fifth appear at
the end of the measure, and the D is an embellishing tone); the ninth is the G on the second beat.
For MM7 or mm7 chords, the added ninth is usually a M9. In the case of the dominant seventh
chord, it may be either a m9 or a M9 (as here). If you are writing in four voices and need to leave
out one chord tone, omit the fifth. You may also find symbols for eleventh or thirteenth chords
in some lead sheets. Simply add the eleventh (a P4) or thirteenth (a M6 or m6) above the bass
to spell these chords.
ninth
In addition to add6 and ninth chords, a third type of chord you may encounter in popular music
is a sus (or sus4) chord; the chord might be labeled B b sus or B b sus4. In these chords, a fourth
replaces the third in a triad: for example, Fsus is spelled F–B b –C rather than F–A–C, making a
dissonance that adds color to the harmony. (Sus chords are named for the suspension, an embel-
lishment in classical style.) Example 12.15, from “Somewhere Out There,” shows a sus chord in
measure 2: the G7sus chord includes a C (fourth above G) retained throughout the measure.

You can also use chord symbols to indicate inversions. Measures 1 and 3 of Example 12.15 illus-
trate how chord inversions are labeled: Cmaj7/E (m. 1) means to play a C major seventh chord
in first inversion, with an E in the bass. Likewise, C/E (m. 3) means to play a C major triad with
E in the bass. The C/F in measure 2 indicates there is a C triad over an F bass note—a passing
tone in the bass part. You should now have a sufficient understanding of chord symbols to spell
most chords you will find in a standard lead sheet.
Finally, as we near the end of this text, we challenge you to continue exploring music—by lis-
tening, playing, singing, and writing. Take some of the harmonies, forms, and styles introduced
in the last two chapters and write some music of your own. Be curious, take more courses, and
above all, experience music of many styles, periods, and regions. In the twenty-first century, the
whole world of music is open to you. Explore and enjoy!

3. Blues scales
To write a blues scale, treat its letter name (A b , for example) as the tonic of a major key, and write the blues scale using that key
signature (four flats). The blue notes— b ^3, # 4^/ b 5^, and b 7^—will always require accidentals, no matter what the key signature.
do me fa fi sol te do do te sol se fa me do
1^ b ^3 4^ # 4^ 5^ b 7^ 1^ 1^ b 7^ 5^ b 5^ 4^ b ^3 1^
Now perform an ascending and descending blues scale from each note below. As you play, sing in a comfortable register with
solfège syllables, scale-degree numbers, and letter names. Then notate each scale on your own music paper. Write the key
signature of the major tonic, and notate the accidentals for each blue note.

C. Swung rhythms
For swing melodies 1–3:
■ When there are chord symbols, play the chords at the keyboard. Initially, don’t worry about rhythm or speed, just accuracy.
When you can play the chords accurately, play them in rhythm, even if your tempo is slow.
■ When you can play the chords in rhythm, sing along as you play. If necessary (especially for notes with accidentals), use the
piano to help. 3
■ These melodies may be sung with the eighth notes swung = , and some feature syncopation.
■ Swung rhythms, often used in jazz and blues, can be notated in simple quadruple meter with eighth notes beamed in groups
of four: . Instead they are performed as if they were written in compound quadruple meter

segments.
c. Now look at the larger formal organization of the melody. There is a bracket over measures 1–4. Draw a bracket over each
repetition of this four-measure melodic idea.

Writing a song
Your final project is to compose either a blues song (Assignment 12.3) or a popular song (Assignment 12.4) with lyrics. Use
examples of these song types in your anthology as models. On your own staff paper, notate the song on a lead sheet that shows
the melody, lyrics, and chord symbols. Read the instructions in their entirety (for both types of songs)—many guidelines are
applicable to both styles. Prepare to perform your song, or arrange to have it performed, in class.
General guidelines
■ Write a short introduction. This might consist of the last four measures of the song or a simple chord progression that
establishes a mood.
■ Include a “hook”—a recurring, memorable part of the music, the lyrics of which are often the song’s title.
■ Recall that many song lyrics are about love—trying to find love, being in love, losing a love.
■ Employ text painting appropriate to your lyrics. For example, you might set the word “sun” or “moon” to the highest pitch in
the phrase.
■ Keep your melody and chord symbols simple; performers bring the music to life by embellishing the melodies and chords
more dramatic.
