On the Overture

“Über die Ouvertüre”

Published 1841

Overview

An essay for the Paris Gazette musicale on the history and purpose of the operatic overture. Wagner traces the overture from a mere signal that singing will begin to the masterpieces of Gluck, Mozart, Cherubini, Beethoven and Weber, contrasts the Don Giovanni Overture with the Leonore Overture, and concludes that the ideal overture should express the drama’s leading idea through purely musical means, as Gluck’s overture to Iphigénie en Aulide does.

From Prologue to Overture

In earlier times, Wagner notes, a spoken prologue prepared the audience for the play, appealing to its imagination and summarising the story. Opera replaced it with an orchestral prelude, but instrumental music was too undeveloped to fill that role, and these early pieces seem only to tell the audience that singing is about to begin. Later overtures hinted at the general mood of the work, but composers were limited to fugue, leaving the listener to deduce the drama’s mood from counterpoint; Handel’s overture to Messiah, he says, could never be taken as a true introduction. The three-part Italian “symphony,” with a slow section between two fast ones, was a step forward, and Mozart’s overture to Die Entführung aus dem Serail is a model of it.

Gluck and Mozart

The perfect form of overture, welding contrasting motives into one unbroken whole, was created by Gluck and Mozart. Gluck’s finest example is the overture to Iphigénie en Aulide, which sketches the drama’s main ideas with almost visible clarity. Mozart, “with the eye of a veritable poet,” grasped the drama’s central thought, stripped it of all incidental detail, and recreated it as “a passion personified in tones,” an independent musical work. Most of his overtures have a full close, but the Don Giovanni Overture flows directly into the first scene, a fitting ending for this particular drama.

Cherubini, Beethoven and Weber

Cherubini kept to this inherited type, though his overture to Les deux journées shows that even the outcome of a stirring plot can be expressed in it. Beethoven’s Fidelio Overture in E is related to Cherubini’s, but in the Leonore Overture Beethoven, lacking a proper outlet for his dramatic genius, let his imagination create the whole drama in tones. “This work is no longer an overture, but the mightiest of dramas in itself.” Weber followed Beethoven and Cherubini, and with Oberon created a new type, the “dramatic fantasia.” Spontini’s overture to La Vestale, however, marks the beginning of the “potpourri,” a string of the opera’s most effective tunes, as in Rossini’s William Tell and Hérold’s Zampa, works that belong to the history of theatrical entertainment rather than art.

Don Giovanni and Leonore Compared

Wagner compares the two supreme examples. The Don Giovanni Overture presents the drama’s leading idea in two purely musical features, a passionate burst of arrogance in conflict with the threats of an implacable higher power, and lets us only sense the outcome as both yield to a higher will in the transition to the first scene. It contains nothing tied to specific events in the plot. The Leonore Overture, by contrast, makes us feel we are watching a real action unfold. Wagner describes it vividly: a dark dungeon, the sighs of a soul longing for freedom, the glance of an angel of rescue who is only a loving woman struggling against obstacles and her own weakness, until the last bolt falls, the sunlight streams in, and the cry of “Freedom!” rings out. Yet because it anticipates the entire drama, it is not a model overture: it is either misunderstood by those who do not know the story, or weakens the drama that follows.

The Ideal Overture

The best approach, Wagner concludes, is that of Don Giovanni: to express the drama’s leading thought in purely musical form, without stepping beyond the limits of music, while still forming a complete work with a definite close. Gluck’s Iphigénie en Aulide is the clearest model. Its heavy unison theme represents the united Greek army bent on its great enterprise, its second theme the suffering individual, the tender maiden to be sacrificed, and the contrast fills us with terror and pity in turn, like Greek tragedy itself. The two themes may struggle toward a resolution in keeping with the drama, as in the overtures to Les deux journées, Fidelio, Egmont, Coriolan and Der Freischütz, but their development must come from their musical nature, not the order of events in the plot.

A composer may weave in musical features that play a decisive role in the drama, such as the priests’ trombones in The Magic Flute, the trumpet call in Leonore and the magic horn in Oberon. The composer, like a philosopher, is concerned with the victory of an idea, not the personal fate of the hero, as the Egmont Overture shows. The one great exception is the Coriolan Overture, where the tragedy lies in the hero’s personal downfall. Beethoven, however, stands alone and inimitable, and Wagner ends by naming Gluck, Mozart and Beethoven together as the guiding star for all composers, warning that anyone who follows only one of them will lose his way.
