OstinatoIn music, an ostinato (ostiˈnaːto; derived from Italian word for stubborn, compare English obstinate) is a motif or phrase that persistently repeats in the same musical voice, frequently in the same pitch. Well-known ostinato-based pieces include classical compositions such as Ravel's Boléro and the Carol of the Bells, and popular songs such as Donna Summer and Giorgio Moroder's "I Feel Love" (1977), Henry Mancini's theme from Peter Gunn (1959), The Who's "Baba O'Riley" (1971), and The Verve's "Bitter Sweet Symphony" (1997).
Program musicProgram music or programmatic music is a type of instrumental art music that attempts to musically render an extramusical narrative. The narrative itself might be offered to the audience through the piece's title, or in the form of program notes, inviting imaginative correlations with the music. A well-known example is Sergei Prokofiev's Peter and the Wolf. The genre culminates in the symphonic works of Richard Strauss that include narrations of the adventures of Don Quixote, Till Eulenspiegel, the composer's domestic life, and an interpretation of Friedrich Nietzsche's philosophy of the Übermensch, Also Sprach Zarathustra.
Nadia BoulangerJuliette Nadia Boulanger (ʒyljɛt nadja bulɑ̃ʒe; 16 September 1887 22 October 1979) was a French music teacher and conductor. She taught many of the leading composers and musicians of the 20th century, and also performed occasionally as a pianist and organist. From a musical family, she achieved early honours as a student at the Conservatoire de Paris but, believing that she had no particular talent as a composer, she gave up writing music and became a teacher.
Benjamin BrittenEdward Benjamin Britten, Baron Britten (22 November 1913 – 4 December 1976, aged 63) was an English composer, conductor, and pianist. He was a central figure of 20th-century British music, with a range of works including opera, other vocal music, orchestral and chamber pieces. His best-known works include the opera Peter Grimes (1945), the War Requiem (1962) and the orchestral showpiece The Young Person's Guide to the Orchestra (1945). Born in Lowestoft, Suffolk, the son of a dentist, Britten showed talent from an early age.
PolytonalityPolytonality (also polyharmony) is the musical use of more than one key simultaneously. Bitonality is the use of only two different keys at the same time. Polyvalence or polyvalency is the use of more than one harmonic function, from the same key, at the same time. Some examples of bitonality superimpose fully harmonized sections of music in different keys. Lithuanian traditional singing style sutartines is based on polytonality.
Microtonal musicMicrotonal music or microtonality is the use in music of microtones—intervals smaller than a semitone, also called "microintervals". It may also be extended to include any music using intervals not found in the customary Western tuning of twelve equal intervals per octave. In other words, a microtone may be thought of as a note that falls between the keys of a piano tuned in equal temperament. Microtonal music can refer to any music containing microtones.
