Lesson 4: Fight Preconceptions with Pentatonic Mode

If you have ever improvised using the five-tone “blues row,” or limited your improvisations to the five black keys of the keyboard, you have experienced the freedom of pentatonic improvising. Hopefully, you found it “goof-proof.” You won’t find a harsh dissonance or non-melodic line in pentatonic mode.

There is a story in my family of a grandmother who bought a piano, and expected to be able to just sit down and play it. Wasn’t that also the mindset of The Music Man, when he first raised his baton to the novice band in River City? And why do people not “just play?” Do we not all have musical and rhythmic intuition?

Composer Carl Orff developed a way of tapping into children’s sense of rhythm and melody. He tuned percussive instruments to the pentatonic scale, and encouraged children to play them, ensemble. Technique was not a problem, given the instruments. Dissonance was not a problem, given the pentatonic scale. When I first heard the results on a recording, I was astounded. Not only was the result rich and appealing, it was also easily imitated, conceptually. It was a music of organized patterns–ostinato and melody patterns, not unconcerned with traditional harmonic structure, but certainly able to transcend traditional music limitations.

To repeat this experiment, it remains only to apply the procedures outlined in Lesson 3 on this website. Pianists may easily improvise using the piano’s black keys, a built-in pentatonic tone row and the “Braille” of the piano. After reviewing this article, guitarists should also see this guitar link.

Some ways pentatonic improvising can work

I. Establish patterns in your ostinato.

A. Select a harmonic structure.

1. For simplicity, use the 5-tone pentatonic scale.
The pentatonic scale is built into the black keys (the “Braille”) of the piano.

A black key takes its sharp and flat names from its nearby white keys.

2. Experiment with intervals.
Tonal intervals are named for the whole- and half-step distance between the tones.

A 5th is more stable than a 4th although the tones are the same.

When you anticipate the distinctive sound of interval tones, played together, you’ll find your improvisations becoming ever more intentional. You’ll have at your disposal:

  • Crunchy tone clusters built of Major 2nds, their obstreperous upside down partners, the minor 7ths, or any number of black keys played at once.
  • Soft minor 3rds and their inversions, major 6ths.
  • The more extroverted major 3rd or its inversion, the minor 6th.
  • The unstable Perfect 4th, or its mirror image, the very stable and consonant Perfect 5th, or “open” 5th.
  • Single tones, or the octave (Perfect 8th).

B. Select a rhythmic structure.

  • Plan and clap your rhythmic pattern, keeping it the same for each measure. (You may wish to refer to Lesson 3, on the ostinato.)
  • Add your chosen harmonic pattern.

Surprisingly, improvisors playing as a group, in pentatonic, can play many ostinatos at the same time, without conflict. If the basic beat is kept, the rhythmic patterns will seem interactive. The complexity of many ostinatos going at once is engaging.

C. Consider a home tone.

Black key open 5ths may be formed from C#, D#, F#, and G#, but not A#.

White key open 5ths are formed from C, D, E, F, G, and A,but not B.
White key open 5ths are formed from C, D, E, F, G, and A,but not B.

To establish a certain mood for your improvisation, select one tone as a home tone, and begin and end the improvisation with that tone. To emphasize the home tone:

  • Play it in the ostinato on the first beat of each measure.
  • Play the home tone together with the 5th tone above it, to make it an “open 5th.”
    • Note that four open fifths are available in pentatonic music (see sidebar).
    • Note that each of the four open fifths will give a very different character to the same pentatonic tune.
    • End the improvisation on an open fifth or octave.

II. Weave your melody where it will be heard over the ostinato.

III. Expect the creative process:

A. Experience: Play pentatonic tones in rhythm

  • Use the beat or rhythm of your ostinato but change it a little.
  • Use the rhythm of a poem.
  • Make your melodic rhythm at least two measures long and pause at the end of that melodic phrase.

B. Discover: Listen carefully and find patterns you like.

C. Explore: Repeat and vary melodic patterns you like.

  • Explore patterns at random.
  • Repeat on the same or different tones.
  • Play upside down or backwards (in inversion or retrograde).
  • Mix longer and shorter patterns.

To harp on a beginner’s trap: It’s extremely important to remember to stop the melody at the end of a phrase, while the ostinato may keep on going. It can be important to make sure there is a rhythm in the melody, so it does not just play on every beat which the ostinato is keeping.

Enrich your understanding by example and further study.

Starting a new activity is always harder than actually doing it. The only way to do it is to just try it out with the instrument you have available. The trying out, regardless of what instrument or training may be available, is what builds your ability to do it more and with more depth. Nevertheless, one can quickly enlarge one’s imagination with study of some guides or examples, such as those that follow.

As referenced in Lesson 3, Michael Nyman’s piano score for Jane Campion’s film, The Piano uses structures and styles Nyman felt the pianist, Ada, would have known. These include structures of pentatonic mode and ostinatos, and styles of 19th century and Scottish music. Use of these elements strongly suggests that Ada is improvising. One might guess that the story’s use of black keys to buy back the piano is an allusion to black key (pentatonic) improvising. Nyman’s piano score is a good example of how an intermediate or advanced improvisor might work with a specific vocabulary of sound for self-expression and growth, at times using pentatonic mode.

The Creative Music books, used in the Robert Pace piano teaching method along with his Music for Piano series, provide detailed exercises for piano students, in manipulating patterns and forms of music.

This chapter has dealt with polyphonic pentatonic music, in terms of improvising both melody and accompaniment. Lesson 5 is contemplated to take a further look at intervals, and discuss their use in monophonic pentatonic melody.

Historical Perspective

When one experiences the simplicity of making pleasing melodies and harmonies on the pentatonic scale, one might surmise it is this simplicity that promoted its common use in folk music around the world, for centuries. Musicologists have collected pentatonic folk music from locations as diverse as China, Japan, Russia, Ireland, Scotland, Finland, Hungary, Turkey, Africa, and the Americas. Anthropologists and archeologists have found ancient flutes with apparent pentatonic and diatonic tunings, two notable examples dating back at least 30,000 years.

Contemporary musicians have not overlooked the pentatonic, although it is often used with an underpinning of diatonic harmony or with the addition of diatonic ornamental tones. Examples would include music of the Beatles, Elvis Presley, and, of course, the blues style.

It’s interesting to speculate that early instrument designers knew about the semitones in the diatonic scale and chose to omit them. While other five-tone scale divisions are possible, the common pentatonic tuning parallels the tones in the diatonic scale. The widespread use of this pentatonic tuning of instruments (such as in primitive flutes) could have developed, in part, from an understanding that polyphonic (many sounds at once) group music is more harmonious if the two semitones are omitted.
