Motif in Music
Structural Uses Of A Motif
Even among those uncomfortable with such anthropomorphic analysis, there is widespread recognition of the motif's role in creating unity within large or disparate pieces. Navajo traditions include an enormous body of Yeibichai songs, representing sacred ancestral spirits. Every one of the songs includes the call of the ancestors, a motif sung to the syllables "Hi ye, hi ye, ho-ho ho ho!" The Quechan tribe, in contrast, sings songs about natural history and lore, grouped into large cycles or series. In their Bird Series, all the songs are related by ending with the same "ha ha ha haaa" motif.
Melodic motifs have functioned structurally in many genres of music. The chief architectonic technique used by Renaissance composers of multivoice masses and motets was imitative counterpoint, in which subsequent voices repeated or echoed the opening motif presented by the initial singer. Similarly, in a Baroque fugue, the work begins with a subject that is reiterated in different registers, and the same motif reenters at later points in the work to start new series of imitative entrances.
Opera composers of the seventeenth and eighteenth centuries wrote arias with "motto openings," in which the first phrase of the song was performed by the singer, followed by a contrasting instrumental passage; the vocalist repeated the same opening phrase but then continued on with the remainder of the aria. In contrast, a single motif may serve as an introductory flourish for an entire set of pieces, such as the multiple movements of some Renaissance masses written in cyclical form, by having each movement begin with the same "head motif" or "motto."
Another common use of mottoes, especially in instrumental music, is the repetition of a clear-cut opening motif to signal important structural points within a movement. The slow, solemn fanfare that begins the first movement of Beethoven's "Pathétique" Sonata, Op. 13, is followed by the fast main section—the exposition—but it returns twice to underscore the start of the movement's development (tonally unstable) and coda (concluding) sections.
Many cultures use certain harmonic motifs to provide a sense of completion or finality. In Western art music, these motifs are often described as cadence "formulas"; one of the most familiar of these is the Plagal (or "Amen") cadence that concludes hymns and other church music. Because cadence formulas are so ubiquitous, composers frequently embellish and prolong them in elaborate ways.
Harmonic motifs also occur in many styles of jazz music. Jazz performers often take the sequence of harmonies (or chord changes) underpinning a tune and use those borrowed chords as the basis for new melodic improvisations. The chords of George Gershwin's Broadway show tune "I Got Rhythm" (1930) are an especially popular source; numerous jazz hits have been based on these particular chord changes.
The organization of rhythm into recognizable groupings is a widespread motivic device. Many music analysts borrow from the vocabulary of poetic meter to describe short patterns of strong and weak pulses in music; thus a short note followed by a longer one would be called an iamb, while a longer note preceding a shorter note is a trochee. It has been traditional in Western literature and music to regard these different rhythms as possessing different emotional qualities.
Cultural customs lead to longer rhythmic patterns in varying contexts. Dances all over the world depend on set rhythmic motifs; a minuet has a different rhythmic pattern than a gavotte or a mazurka. In classical music of India, clap-patterns can be incorporated into a performance in accordance with one of the ancient rhythmic patterns, known as a tala. The complicated layering of much African drumming consists of the simultaneous presentation of diverse rhythmic motifs by various players, often repeated in ostinato fashion.
In numerous cultures, a motif may carry symbolic meaning. Much of India's classical music, for example, is based on rāgas. Each rāga combines aspects of a mode—a certain set of pitches—with particular melodic motifs. Rāgas carry extramusical associations, sometimes linked to emotions, divinities, and even particular seasons of the year or times of day. Similarly the leitmotifs (leading motives) that Richard Wagner used in the four music dramas of his opera cycle Der Ring des Nibelungen (The ring of the Nibelungs; 1848–1874) are linked with a person, an object, or even an idea, and were repeated at different points in the work to bring that association back to our minds. For instance, in Die Walküre (the second music drama in the cycle), when Wotan refers to a "hero to come," the orchestra sounds the motif linked with Siegfried (even though at that point Siegfried has not yet been born).
Motifs can also portray more than just characters and objects in a story; at times, motifs have represented composers themselves. Since, in German musical nomenclature, the note B-flat is transcribed as a "B" and B-natural is transcribed as an "H," Johann Sebastian Bach was able to use a motif based on the letters of his last name as a subject for a fugue. Many other composers have embedded motivic messages into their works through this type of cryptography.
Despite its often tiny size, the motif's diversity makes it one of the most powerful tools at the disposal of composers and performers. It is one of the few musical characteristics that can be found in virtually all world cultures as well as throughout recorded history. Perhaps most important for listeners, a motif is a device by which music gains cohesion and, often, comprehensibility.
