Question: In music, an ostinato, is a motif or phrase that persistently repeats in the same musical voice, usually at the same pitch, well-known ostinato-based pieces include both classical compositions such as Donna Summer, was an American singer, songwriter, and painter, and she gained prominence during the disco era of which late era?

full_context: Document 1: Music of the African diaspora: Music of the African diaspora was mostly refined and developed during the period of slavery. Slaves did not have easy access to instruments, so vocal work took on new significance. Through chants and work songs people of African descent preserved elements of their African heritage while inventing new genres of music. The culmination of this great sublimation of musical energy into vocal work can be seen in genres as disparate as Gospel Music and Hip-Hop. The music of the African diaspora makes frequent use of ostinato, a motif or phrase which is persistently repeated at the same pitch. The repeating idea may be a rhythmic pattern, part of a tune, or a complete melody. The banjo is a direct decedent of the Akonting created by the Jola people, found in Senegal, Gambia and Guinea-Bissau in West Africa. Hence, the melodic traditions of the African diaspora are probably most alive in Blues and Jazz.

A five-time Grammy Award winner, Summer was the first artist to have three consecutive double albums reach No. 1 on the United States "Billboard" 200 chart and charted four number-one singles in the U.S. within a 12-month period. Summer has reportedly sold over 140 million records worldwide, making her one of the world's best-selling artists of all time. She also charted two number-one singles on the R&B charts in the U.S. and a number-one in the U.K.
Document 3: Stabat Mater (Pergolesi): Stabat Mater is a musical setting of the "Stabat Mater " sequence, composed by Giovanni Battista Pergolesi in 1736.

Document 6: Denver Dream (song): "Denver Dream" is a song by American singer Donna Summer, released in 1974. This was her first collaboration with Giorgio Moroder and Pete Bellotte, a songwriting team that would stay together until 1981 and produce all of Summer's biggest disco hits. At this time Summer was living in Munich, Germany and singing backup for groups such as Three Dog Night. Through her job as a backup singer she met Moroder and before long he started using her as a lead vocalist. This single also marked the first usage of Summer's stage name (she had previously been credited as Donna Gaines, but had anglicised her married name to Austrian actor Helmut Sommer). It was released in The Netherlands, Belgium and France in 1974, but did not make any particular impact on the chart. The B-side, "Something's in the Wind", would, in 1977, be re-worked into the single, "Back in Love Again", which would become a top-40 UK hit. Both sides of this single now appear on the CD compilation "Giorgio Moroder - Vol. 2-On The Groove Train 1974-85"
Document 7: The Journey: The Very Best of Donna Summer: The Journey: The Very Best of Donna Summer is a compilation of the American singer's hits released by Universal Music in 2003. It features most of Summer's best known songs from the 1970s disco era, during which she became the most successful female of that genre, plus some of her hits from the 1980s, during which time she experimented with different genres.

Document 9: Snare rush: Snare rush is a term often used in electro culture to refer to impossibly fast rolls. A snare rush can vary in tempo considerably, from 16th notes even to 2048th notes. At that sort of speed, the effect is a buzzing sound, but with a detectable pitch, so some artists vary the repeat rate, and can even play a tune. One example of this would be the last 18 seconds of "Ghetto Body Buddy" by Venetian Snares, where the theme from "Sesame Street" is played using only extremely fast snare rushes. The defining characteristic of a snare rush, as opposed to a roll, is the sheer virtuosity it would take for a physical drummer to play a successful one. As such, almost all snare rushes are computer programmed and can be used with bass drums, tom-toms, and cymbals to intensify the effect. They are often used as fills, alongside complex programmed breakbeats. Snare rushes are also often run through analog or dsp effects together with variations in volume, such as a filters or pitch shifting. They are common in trance music, hard techno, gabber music, oldschool jungle, IDM, drill 'n bass, breakcore and glitch music.
Document 10: Recitative: Recitative ( , also known by its Italian name "recitativo" (] )) is a style of delivery (much used in operas, oratorios, and cantatas) in which a singer is allowed to adopt the rhythms of ordinary speech. Recitative does not repeat lines as formally composed songs do. It resembles sung ordinary speech more than a formal musical composition.
Document 11: Endless Summer: Donna Summer's Greatest Hits: Endless Summer: Donna Summer's Greatest Hits is a compilation album by Donna Summer, released in 1994. It contains many of her best known songs from her 1970s breakthrough to the present day. Summer is best known for her work during the 1970s disco era, though she released a substantial amount of material in the 1980s and 1990s, covering a variety of genres. Unlike 1993's "The Donna Summer Anthology", which had used the majority of the songs in their original, longer forms, "Endless Summer" generally contained the versions of the songs that were used upon their release as a single. However, the version sold in the UK which included "I Don't Wanna Get Hurt" used the album version of the track (from "Another Place and Time"), not the more club-oriented mix released as a 7" single there.
Document 12: Ostinato: In music, an ostinato ] (derived from Italian: "stubborn", compare English, from Latin: 'obstinate') is a motif or phrase that persistently repeats in the same musical voice, usually at the same pitch. Well-known ostinato-based pieces include both classical compositions such as Ravel's "Boléro" and popular songs such as Donna Summer and Giorgio Moroder's "I Feel Love" (1977), Henry Mancini's Theme from Peter Gunn (1959), and The Verve's "Bitter Sweet Symphony" (1997).
Document 13: The Donna Summer Anthology: The Donna Summer Anthology is a double compilation album by the American singer Donna Summer, released by Polygram Records in 1993. The compilation featured the majority of Summer's best known songs right from the start of her success to the present day. Summer had originally made her name during the disco era in the 1970s and in the decade that followed had experimented with different styles. Most of the tracks on this compilation are the original album versions of the songs, which were sometimes edited down for their release as a single. Included for the first time are two remixed tracks from her then previously unreleased I'm a Rainbow album, which had been recorded in 1981 but had been shelved by her record company at the time. The album also featured the Giorgio Moroder-penned and produced song "Carry On"', marking the first time Summer and Moroder had worked together since 1981. Summer and Moroder, together with Pete Bellotte had written the vast majority of her 1970s disco hits. Four years later, "Carry On" would be remixed and become a big dance hit. It also won Summer a Grammy for Best Dance Recording, her first win since 1984 and her fifth win in total.
Document 14: Stutter edit: The stutter edit is an audio software VST plugin, implementing forms of granular synthesis, sample retrigger, and various effects to create a certain audible manipulation of the sound run through it, in which fragments of audio are repeated in rhythmic intervals. "In plain English, a stutter edit contains a single segment of audio repeated a number of times, giving a performance a decidedly digital flavor." Stutter edits not only occur as the common 16th note repetition, but also as 64th notes and beyond. Stutter edits can go beyond 2,048th notes and can be measured in milliseconds. Above a certain point, these repetitions transition from rhythmic to tonal frequencies, making musical notes out of the repeated audio. These extremely short, fast groups of notes are often placed into the spacing of an eighth or sixteenth note in an otherwise “normal” bar, creating rhythmic accenting and patterns that call attention to a particular section. These patterns can be placed at the beginning of a bar, or towards the end for a more syncopated sound. One example is in the second verse of "Drop It Like It's Hot", Snoop mentions a DJ followed by a stutter edit and turntable scratch in reply.
Document 15: Cantabile: In music, cantabile ] , an Italian word, means literally "singable" or "songlike". In instrumental music, it is a particular style of playing designed to imitate the human voice. For 18th-century composers, cantabile is often synonymous with "cantando" (singing), and indicates a measured tempo and flexible, legato playing. For later composers, particularly in piano music, cantabile is the drawing out of one particular musical line against the accompaniment (compare counterpoint). Felix Mendelssohn's six books of "Songs Without Words (Lieder ohne Worte)" are short lyrical piano pieces with song-like melodies written between 1829 and 1845. A modern example is an instrumental by Harry James & His Orchestra, called "Trumpet Blues and Cantabile".
