Emphasis is very important in communication: It helps to establish what is of primary importance, versus what may be supporting or of secondary relevance.
Verbal communication contains a variety of strategies for creating emphasis. For instance, you’re instructing your children on pool safety: Don’t run next to the pool, no splashing in other people’s faces, etc. But most important of all: No children allowed in the water without a grown-up. How would you emphasize this statement’s import? You might repeat it several times; you might raise your voice; you might grab your child’s hand and look him or her in the eye; you might sit the child, down, pause, and then speak.
How is emphasis created in a piece of music? Being able to recognize and interpret such emphases is essential to active listening. When a composer is communicating with you through music, it is very helpful to know what he or she considers to be of primary importance.
Musical emphasis may be created by duration, change and extremes. When emphases are coordinated to help illuminate musical structure, rhetorical reinforcement is created.
Music is a time-art: Therefore, if you want to emphasize something in a piece of music, make it last. The longer something is before the listeners’ ears, the greater the importance it assumes.
The ends of phrases in this Bach Chorale are emphasized through duration.
Duration is used to emphasize the words “Rote fürßtliche Rubine” in this movement from Arnold Schoenberg’s Pierrot Lunaire.
Repetition creates a durational emphasis. As in the Bach Chorale above, the ends of phrases are emphasized in Chopin’s Prelude in A-Major, only this time the chords are repeated rather than held.
Repetition is used to create two powerful durational emphases in this excerpt from Igor Stravinsky’s The Rite of Spring.
Through repetition and other means of prolongation, durational emphasis can span a whole section of even an entire composition. Marriage is a form of durational emphasis: A favored relationship outlasts passing acquaintances. Similarly, in a piece of music, that which endures has a priority over that which is fleeting. A melodic idea, a rhythmic pattern, a particular texture all may be sustained throughout an entire work.
A rhythmic pattern is prolonged throughout Frederic Chopin’s Piano Prelude in c-minor.
In the third of Elliott Carter’s Eight Etudes and a Fantasy, a single chord is held throughout the entire piece. The instruments constantly shift so that the chord is never voiced the same way twice. Nevertheless, throughout the subtle surface motions, one sound is clearly emphasized by duration.
When listening to music, concentrate on what is most persistent. That which lasts longest is most essential; everything else is supporting. In a non-verbal, time-dependent art form, duration is the composer’s primary means of emphasis.
Change is a second way of creating emphasis. We change into our pajamas to indicate we’re ready to go to sleep. We all notice when the weather changes. If the lights go out, it will catch your attention. If the crowd noise suddenly rises at a sporting match, you will want to know what happened. Likewise, in music, a change—of register, texture, density, speed, dynamic, etc.—will create an emphasis.
In the Berlioz: Requiem, the text “Hosanna in excelsis ” is first sung by high voices and instruments. When low voices and instruments enter, the change in register creates an emphasis.
Similarly, in Kristof Penderecki’s Threnody for the Victims of Hiroshima, each string entrance is emphasized by a change in register.
The greater the change, the greater the emphasis. In the Finale of Tchaikovsky’s Symphony No. 2, the change in density is sudden and dramatic.
In “Danse de la fureur” from Olivier Messaien’s Quartet for the End of Time, a sudden change in dynamics creates a strong emphasis.
The longer a particular state has been maintained, the greater the emphasis of the change.
The opening of Alfred Schnittke’s Concerto Grosso No. 1 begins with spare sounds played on the prepared piano (a piano with objects inserted inside the instrument to make its pitch more undefined). The solo violins enter quietly. But after such a long introduction, a well-marked emphasis is created by the change of instrumentation.
Extremes are another powerful means of emphasis: A moment of silence stresses the solemnity of a memorial service; blaring sirens alert us to the dangers of a fire. A solitary figure on the street highlights the late hour; a standing-room only crowd draws attention to a show’s success.
Musical extremes include fastest and slowest, longest and shortest, highest and lowest, loudest and softest, densest and most spare.
Beethoven’s Violin Concerto begins with the following melody.
Later, the soloist emphasizes the melody by playing it in an extremely high register.
Gyorgy Ligeti’s Desordre presents a melody in the upper register, echoed in the low.
The melody is particularly emphasized when both of the pianist’s hands play in a very high register.
The longer an extreme is maintained, the more emphatic it is.
An emphasis on its own may catch our attention. When several emphases join together to mark an important structural moment, it creates a stronger accentuation that we will term rhetorical reinforcement.
Consider the relation between the film and score in a conventional Hollywood film: The role of score is to support the action. The score helps to underline significant moments in the film by being synchronized with them. If you’re familiar with 007 films, you know who appears on screen at the end of this sound-clip:
When James Bond has appeared, there was a change of texture, a steady pulse was established and new instruments entered. The film and music joined together to create a united emphasis. By virtue of its compounding of emphases, rhetorical reinforcement promotes clarity.
Opera and ballet often have a similar relationship between narrative and music.
The overture of Wolfgang Amadeus Mozart’s Don Giovanni opens with stark chords.
As the stage action begins, Don Giovanni murders the Commendatore, the father of one of his lovers. Many scenes later, Don Giovanni and his servant are scheming in a churchyard when the dead man’s statue issues a warning. Don Giovanni blithely invites the statue to dinner.
The Don is celebrating later at the banquet when the statue of the Commendatore suddenly appears before him. The return of the stark chords--not heard since the overture--heralds the Commendatore’s reappearance: Silence, and abrupt changes in texture and speed contribute to the emphasis. Music and narrative are aligned, creating a powerful dramatic arrival point.
In Francis Poulenc’s Dialogue of the Carmelites, a group of nuns are sentenced to death during the Reign of Terror. As the nuns are marched to the guillotine, they sing a chorale over a march-like rhythmic accompaniment. As each nun is executed, one singer drops out, finally leaving a single voice alone. The march-like rhythm and final female voice drop out with the fall of the blade: Once again, music and narrative are in perfect alignment.
Just as music and story can be coordinated, so too can the various musical dimensions within an abstract musical work: Emphases created by duration, change and extremes can join together to mark significant landmarks. For instance, listen to the following excerpt from Beethoven’s Symphony No. 5. The excerpt will stop on a particular note. In your opinion, is that note emphasized or not?
The note is important relative to what has preceded it. The note is not important relative to what has preceded it.
No musical training or theory is required to hear that the note is strongly emphasized. Just by ear, it is possible to analyze how the rhetorical reinforcement was created.
- It is the longest note so far.
- It is the highest note so far.
- It is the loudest note so far.
- The timpani and brass enter.
- As the note is held, there is a dramatic change in texture from full orchestra to the violins alone.
By aligning emphases of duration, register, dynamics and orchestration, Beethoven has used a compounding of emphases to stress the arrival pitch. The pitch’s importance is impossible to miss, because Beethoven has put so much musical muscle behind it.
Rhetorical reinforcement is frequently used to highlight the beginning of a new section or the return of an important passage. Listen to the main theme of the first movement of Beethoven’s Symphony No. 2.
We will now fast forward to later in the movement. Do you recognize the return of the opening? What rhetorically reinforces it?
After an intense flurry of activity, the rhythm suddenly stopped. The texture and dynamics changed. The musical dimensions shifting in coordination signaled that an important formal arrival was taking place.
The Finale of Bartok’s Concerto No. 1 begins with the following explosive theme.
Once again, we will fast forward to later in the movement. Once again, do you recognize the return of the opening? What rhetorically reinforces it?
Once again, a compounding of emphases marked the return: The rhythm stopped; there was a loud cymbal crash, followed by a dramatic change in volume and texture. Rhetorical reinforcement has created an unmistakable formal landmark.
The Reinforcement of Extremes
When extremes reinforce each other, they create a particularly strong emphasis.
In his Symphony in D, Cesar Franck uses extremes of volume and density to emphasize two appearances of his main theme. The theme is initially played softly and sparely.
It returns later, this time played loudly by the full orchestra.
Similarly, in Rituel, Pierre Boulez introduces his primary theme in the solo oboe, with a sparse accompaniment.
Later, the theme echoes between different instrumental groups, in a prolonged statement made powerful by is massive density and loud volume.
When the greatest number of extremes coincides, a climax is created. A climax is the “most of the mosts:” It represents a work’s maximum emphasis.
The Finale of Igor Stravinsky’s The Firebird begins with the following theme:
Stravinsky brings the work to a close by using maximum repetition, volume, density and speed—both fast and slow--to create a majestic emphasis.
A climax typically highlights that which is most essential: It gives you the most direct, powerful statement of a work’s main idea.
In Alban Berg’s opera Wozzeck, the beleaguered soldier Wozzeck becomes convinced of his wife’s infidelity. He lures his wife to a deserted lake and stabs her. Throughout the scene, as Wozzeck is contemplating his wife’s murder, a fixed pitch hovers perpetually in the background. After Wozzeck has slain his wife, Berg creates one of the most spectacular and climactic rhetorical reinforcements in music history: The fixed pitch swells in intensity until it consumes the entire orchestra. Emphases of duration, volume, register and density are all joined together. That which is most essential is given its strongest emphasis.
The Absence of Rhetorical Reinforcement
When a player for the home team hits a home run, the crowd rises to its feet cheering, music plays, the scoreboard flashes a replay: Strong rhetorical reinforcement occurs. But if a player for the visiting team hits a home run, the stadium is quiet: No one cheers, no sirens go off, no replays are shown. The fans refuse to acknowledge that an important event has occurred. There is an absence of rhetorical reinforcement.
Such equanimity is crucial when you play cards: If you are dealt four aces, it is important to maintain a “poker face,” betraying no hint of your good fortune.
Similarly, in music, it is possible for the rhetorical reinforcement to be weak or absent.
Listen to the opening of Schubert’s Quintet in C for two violins, viola and two cellos.
Once again, we will fast forward to later in the movement. Do you recognize the return?
You may have hesitated this time. Why? This time, the rhetorical reinforcement is much less emphatic.
At the opening, the strings move together in very slow values.
At the return, the instruments should change speed, texture and dynamic together. But the first violin does not cooperate! Instead, it continues with its pattern from the previous section. Thus, a united emphasis does not take place: The first violin is out-of-phase with the other instruments, creating a weaker acknowledgment of the form.
Whereas strong rhetorical reinforcement promotes clarity, weak or absent rhetorical reinforcement creates ambiguity. The degree of rhetorical reinforcement is one of the strongest measures of compositional intent. Schubert could have created a strongly articulated return. However, he chose to maintain a “poker face,” making the return less obvious. Why? This question can become a point-of-entry into a more in-depth study of the piece.
Climaxes depend on coordination between the musical dimensions. As a result, highly unrhetorical music will tend not to have a climax: The different dimensions are too out-of-phase from one another to create a clear structural alignment. In Morton Feldman’s Why Patterns?, the three players—flute, glockenspiel and piano—are instructed to proceed independently through the score. The synchronization of the players varies from one performance to the next; each time, the combination of the parts is unique. Under such conditions, rhetorical reinforcement and a reliable climax are impossible to produce. Feldman related this to the absence of perspective in Abstract Expressionist art: He wrote of “flattening the aural canvas” so that it lacked rhetorical peaks.
Duration, change and extremes are primary ways of creating emphasis in a musical composition. Being alert to such emphases--how they are created and what they are signaling—helps you to recognize significant musical events. When emphases are aligned to signal a formal landmark, rhetorical reinforcement is created.b Strong rhetorical reinforcement promotes clarity; weak or absent rhetorical reinforcement promotes ambiguity.
