Repetition (music)

A chant (from French chanter, from Latin cantare, "to sing") is the iterative speaking or singing of words or sounds, often primarily on one or two main pitches called reciting tones. Chants may range from a simple melody involving a limited set of notes to highly complex musical structures, often including a great deal of repetition of musical subphrases, such as Great Responsories and Offertories of Gregorian chant. Chant may be considered speech, music, or a heightened or stylized form of speech. In the Late Middle Ages, some religious chant evolved into song (forming one of the roots of later Western music).

Rhythm (from Greek ῥυθμός, rhythmos, "any regular recurring motion, symmetry") generally means a "movement marked by the regulated succession of strong and weak elements, or of opposite or different conditions". This general meaning of regular recurrence or pattern in time can apply to a wide variety of cyclical natural phenomena having a periodicity or frequency of anything from microseconds to several seconds (as with the riff in a rock music song); to several minutes or hours, or, at the most extreme, even over many years.

The Oxford English Dictionary defines rhythm as "The measured flow of words or phrases in verse, forming various patterns of sound as determined by the relation of long and short or stressed and unstressed syllables in a metrical foot or line; an instance of this".

In music, form refers to the structure of a musical composition or performance. In his book, Worlds of Music, Jeff Todd Titon suggests that a number of organizational elements may determine the formal structure of a piece of music, such as "the arrangement of musical units of rhythm, melody, and/or harmony that show repetition or variation, the arrangement of the instruments (as in the order of solos in a jazz or bluegrass performance), or the way a symphonic piece is orchestrated", among other factors. It is, "the ways in which a composition is shaped to create a meaningful musical experience for the listener."

These organizational elements may be broken into smaller units called phrases, which express a musical idea but lack sufficient weight to stand alone. Musical form unfolds over time through the expansion and development of these ideas. In tonal harmony, form is articulated primarily through cadences, phrases, and periods. "Form refers to the larger shape of the composition. Form in music is the result of the interaction of the four structural elements," of sound, harmony, melody, and rhythm.

In music, tension is the anticipation music creates in a listener's mind for relaxation or release. For example, tension may be produced through reiteration, increase in dynamic level, gradual motion to a higher or lower pitch, or (partial) syncopations between consonance and dissonance.

Experiments in music perception have explored perceived tension in music, and perceived emotional intensity.

In music, a repeat sign is a sign that indicates a section should be repeated. If the piece has one repeat sign alone, then that means to repeat from the beginning, and then continue on (or stop, if the sign appears at the end of the piece). A corresponding sign facing the other way indicates where the repeat is to begin. These are similar to the instructions da capo and dal segno.

Ambient music is a genre of music that emphasizes tone and atmosphere over traditional musical structure or rhythm. Often "peaceful" sounding and lacking composition, beat, and/or structured melody, ambient music uses textural layers of sound that can reward both passive and active listening, and encourage a sense of calm or contemplation. The genre evokes an "atmospheric", "visual", or "unobtrusive" quality. Nature soundscapes may be included, and some works use sustained or repeated notes, as in drone music. Bearing elements associated with new-age music, instruments such as the piano, strings and flute may be emulated through a synthesizer.

The genre originated in the 1960s and 1970s, when new musical instruments were being introduced to a wider market, such as the synthesizer. It was presaged by Erik Satie's furniture music and styles such as musique concrète, minimal music, Jamaican dub music and German electronic music, but was prominently named and popularized by British musician Brian Eno in 1978 with his album Ambient 1: Music for Airports; Eno opined that ambient music "must be as ignorable as it is interesting", however, in early years, there were artists that were pioneers in this genre, like Tangerine Dream, Klaus Schulze, Wendy Carlos, Kraftwerk, etc. It saw a revival towards the late 1980s with the prominence of house and techno music, growing a cult following by the 1990s.

Minimal music (also called minimalism) is a form of art music or other compositional practice that employs limited or minimal musical materials. Prominent features of minimalist music include repetitive patterns or pulses, steady drones, consonant harmony, and reiteration of musical phrases or smaller units. It may include features such as phase shifting, resulting in what is termed phase music, or process techniques that follow strict rules, usually described as process music. The approach is marked by a non-narrative, non-teleological, and non-representational approach, and calls attention to the activity of listening by focusing on the internal processes of the music.

The approach originated on the West Coast of the United States in the late 1950s and early 1960s, particularly around the Bay Area, where La Monte Young, Terry Riley and Steve Reich were studying and living at the time. After the three composers moved to the East Coast, their music became associated with the New York Downtown music scene of the mid-1960s, where it was initially viewed as a form of experimental music called the New York Hypnotic School. In the Western art music tradition, the American composers Moondog, La Monte Young, Terry Riley, Steve Reich and Philip Glass are credited with being among the first to develop compositional techniques that exploit a minimal approach. The movement originally involved dozens of composers, although only five (Young, Riley, Reich, Glass, and later John Adams) emerged to become publicly associated with American minimal music; other lesser known pioneers included Dennis Johnson, Terry Jennings, Richard Maxfield, Pauline Oliveros, Phill Niblock, and James Tenney. In Europe, the music of Louis Andriessen, Karel Goeyvaerts, Michael Nyman, Howard Skempton, Éliane Radigue, Gavin Bryars, Steve Martland, Peter Michael Hamel, Henryk Górecki, Arvo Pärt and John Tavener exhibits minimalist traits.

Terrence Mitchell Riley (born June 24, 1935) is an American composer and performing musician best known as a pioneer of the minimalist school of composition. Influenced by jazz and Indian classical music, his work became notable for its innovative use of repetition, tape music techniques, improvisation, and delay systems. His best known works are the 1964 composition In C and the 1969 album A Rainbow in Curved Air, both considered landmarks of minimalism and important influences on experimental music, rock, and contemporary electronic music. Subsequent works such as Shri Camel (1980) explored just intonation.

Raised in Redding, California, Riley began studying composition and performing solo piano in the 1950s. He befriended and collaborated with composer La Monte Young, and later became involved with both the San Francisco Tape Music Center and Young's New York collective, the Theatre of Eternal Music. A three-record deal with CBS in the late 1960s brought his work to wider audiences. In 1970, he began intensive studies under Hindustani singer Pandit Pran Nath, whom he often accompanied in performance. He has collaborated frequently throughout his career, most extensively with chamber ensemble the Kronos Quartet and his son, guitarist Gyan Riley.

Stephen Michael Reich (/raɪʃ/ RYSHE; born October 3, 1936) is an American composer best known as a pioneer of minimal music in the mid to late 1960s. Reich's work is marked by its use of repetitive figures, slow harmonic rhythm, and canons. Reich describes this concept in his essay "Music as a Gradual Process" by stating, "I am interested in perceptible processes. I want to be able to hear the process happening throughout the sounding music." For example, his early works experiment with phase shifting, in which one or more repeated phrases plays slower or faster than the others, causing it to go "out of phase." This creates new musical patterns in a perceptible flow.

His innovations include using tape loops to create phasing patterns, as on the early compositions It's Gonna Rain (1965) and Come Out (1966), and the use of simple, audible processes, as on Pendulum Music (1968) and Four Organs (1970). Works like Drumming (1971) and Music for 18 Musicians (1976), both considered landmarks of minimalism and important influences on experimental music, rock, and contemporary electronic music, would help entrench minimalism as a movement. Reich's work took on a darker character in the 1980s with the introduction of historical themes as well as themes from his Jewish heritage, notably Different Trains (1988).

In music, the conclusion is the ending of a composition and may take the form of a coda or outro.

Pieces using sonata form typically use the recapitulation to conclude a piece, providing closure through the repetition of thematic material from the exposition in the tonic key. In all musical forms other techniques include "altogether unexpected digressions just as a work is drawing to its close, followed by a return...to a consequently more emphatic confirmation of the structural relations implied in the body of the work."

Da capo (/dɑː ˈkɑːpoʊ/ dah KAH-poh, US also /də -/ də -⁠, Italian: [da (k)ˈkaːpo]; often abbreviated as D.C.) is an Italian musical term that means "from the beginning" (literally, "from the head"). The term is a directive to repeat the previous part of music, often used to save space, and thus is an easier way of saying to repeat the music from the beginning.

In small pieces, this might be the same thing as a repeat. But in larger works, D.C. might occur after one or more repeats of small sections, indicating a return to the very beginning. The resulting structure of the piece is generally in ternary form. Sometimes, the composer describes the part to be repeated, for example: Menuet da capo. In opera, where an aria of this structure is called a da capo aria, the repeated section is often adorned with grace notes.

In music, imitation is the repetition of a melody in a polyphonic texture shortly after its first appearance in a different voice. The melody may vary through transposition, inversion, or otherwise, but retain its original character. The intervals and rhythms of an imitation may be exact or modified; imitation occurs at varying distances relative to the first occurrence, and phrases may begin with voices in imitation before they freely go their own ways.

Imitation helps provide unity to a composition and is used in forms such as the fugue and canon.

In the theory of musical form, through-composed music is a continuous, non-sectional, and non-repetitive piece of music. The term is typically used to describe songs, but can also apply to instrumental music.

While most musical forms such as ternary form (ABA), rondo form (ABACABA), and sonata form (ABA') rely on repetition, through-composed music does not re-use material (ABCD). This constant introduction of new material is most noticeable in musical settings of poems, in contrast to the often used strophic form (AAA). Through-composed songs have different music for each stanza of the lyrics. The German word durchkomponiert is also used to indicate this concept.

In music, a pedal point (also pedal note, organ point, pedal tone, or pedal) is a sustained tone, typically in the bass, during which at least one foreign (i.e. dissonant) harmony is sounded in the other parts. A pedal point sometimes functions as a "non-chord tone", placing it in the categories alongside suspensions, retardations, and passing tones. However, the pedal point is unique among non-chord tones, "in that it begins on a consonance, sustains (or repeats) through another chord as a dissonance until the harmony", not the non-chord tone, "resolves back to a consonance".

Pedal points "have a strong tonal effect, 'pulling' the harmony back to its root". Pedal points can also build drama or intensity and expectation. When a pedal point occurs in a voice other than the bass, it is usually referred to as an inverted pedal point (see inversion). Pedal points are usually on either the tonic or the dominant (fifth note of the scale) tones. The pedal tone is considered a chord tone in the original harmony, then a nonchord tone during the intervening dissonant harmonies, and then a chord tone again when the harmony resolves. A dissonant pedal point may go against all harmonies present during its duration, being almost more like an added tone than a nonchord tone, or pedal points may serve as atonal pitch centers.

In music and jazz improvisation, a melodic pattern (or motive) is a cell or germ serving as the basis for repetitive pattern. It is a figure that can be used with any scale. It is used primarily for solos because, when practiced enough, it can be extremely useful when improvising. "Sequence" refers to the repetition of a part at a higher or lower pitch, and melodic sequence is differentiated from harmonic sequence. One example of melodic motive and sequence are the pitches of the first line, "Send her victorious," repeated, a step lower, in the second line, "Happy and glorious," from "God Save the Queen".

"A melodic pattern is just what the name implies: a melody with some sort of fixed pattern to it." "The strong theme or motive is stated. It is repeated more or less exactly, but at a different pitch level."
