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?
answer: 1970s
context: Title: The Donna Summer Anthology
  Passage: 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  Summer had originally made her name during the disco era in the 1970s and in the decade that followed had experimented with different styles.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.
  Title: Endless Summer: Donna Summer's Greatest Hits
  Passage: 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.

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.

  Title: Pattie Brooks

She was born in Fort Riley, Kansas to a military family.  Her first break came in 1968 when she auditioned for the chorus on "The Smothers Brothers Comedy Hour".  In the next decade she became a sought-after backing singer, appearing on the Bobby Darin Show and touring with, among others Helen Reddy.  She sang backing on Donna Summer's "I Remember Yesterday" album.
  Title: Music of the African diaspora
  Passage: 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.
  Title: The Journey: The Very Best of Donna Summer
