Olivier Messiaen in the context of "Modes (music)"

In music theory, the term mode or modus is used in a number of distinct senses, depending on context.

Its most common use may be described as a type of musical scale coupled with a set of characteristic melodic and harmonic behaviors. It is applied to major and minor keys as well as the seven diatonic modes (including the former as Ionian and Aeolian) which are defined by their starting note or tonic. (Olivier Messiaen's modes of limited transposition are strictly a scale type.) Related to the diatonic modes are the eight church modes or Gregorian modes, in which authentic and plagal forms of scales are distinguished by ambitus and tenor or reciting tone. Although both diatonic and Gregorian modes borrow terminology from ancient Greece, the Greek tonoi do not otherwise resemble their medieval/modern counterparts.

French opera is both the art of opera in France and opera in the French language. It is one of Europe's most important operatic traditions, containing works by composers of the stature of Rameau, Berlioz, Gounod, Bizet, Massenet, Debussy, Ravel, Poulenc and Messiaen. Many foreign-born composers have played a part in the French tradition, including Lully, Gluck, Salieri, Cherubini, Spontini, Meyerbeer, Rossini, Donizetti, Verdi and Offenbach.

French opera began at the court of Louis XIV with Jean-Baptiste Lully's Cadmus et Hermione (1673), although there had been various experiments with the form before that, most notably Pomone by Robert Cambert. Lully and his librettist Quinault created tragédie en musique, a form in which dance music and choral writing were particularly prominent. Lully's most important successor was Rameau. After Rameau's death, Christoph Willibald Gluck was persuaded to produce six operas for the Paris Opera in the 1770s. They show the influence of Rameau, but simplified and with greater focus on the drama. At the same time, by the middle of the 18th century another genre was gaining popularity in France: opéra comique, in which arias alternated with spoken dialogue. By the 1820s, Gluckian influence in France had given way to a taste for the operas of Rossini. Rossini's Guillaume Tell helped found the new genre of Grand opera, a form whose most famous exponent was Giacomo Meyerbeer. Lighter opéra comique also enjoyed tremendous success in the hands of Boieldieu, Auber, Hérold and Adam. In this climate, the operas of Hector Berlioz struggled to gain a hearing. Berlioz's epic masterpiece Les Troyens, the culmination of the Gluckian tradition, was not given a full performance for almost a hundred years after it was written.

Pierre Louis Joseph Boulez (French: [pjɛʁ lwi ʒozεf bulɛz]; 26 March 1925 – 5 January 2016) was a French composer, conductor and writer, and the founder of several musical institutions. He was one of the dominant figures of post-war contemporary classical music.

Born in Montbrison, in the Loire department of France, the son of an engineer, Boulez studied at the Conservatoire de Paris with Olivier Messiaen, and privately with Andrée Vaurabourg and René Leibowitz. He began his professional career in the late 1940s as music director of the Renaud-Barrault theatre company in Paris. He was a leading figure in avant-garde music, playing an important role in the development of integral serialism in the 1950s, controlled chance music in the 1960s and the electronic transformation of instrumental music in real time from the 1970s onwards. His tendency to revise earlier compositions meant that his body of work was relatively small, but it included pieces considered landmarks of twentieth-century music, such as Le Marteau sans maître, Pli selon pli and Répons. His uncompromising commitment to modernism and the trenchant, polemical tone in which he expressed his views on music led some to criticise him as a dogmatist.

Karlheinz Stockhausen (German: [kaʁlˈhaɪnts ˈʃtɔkhaʊzn̩] ; 22 August 1928 – 5 December 2007) was a German composer, widely acknowledged by critics as one of the most important but also controversial composers of the 20th and early 21st centuries. He is known for his groundbreaking work in electronic music, having been called the "father of electronic music", for introducing controlled chance (aleatory techniques) into serial composition, and for musical spatialization.

Stockhausen was educated at the Hochschule für Musik Köln and the University of Cologne, later studying with Olivier Messiaen in Paris and with Werner Meyer-Eppler at the University of Bonn. As one of the leading figures of the Darmstadt School, his compositions and theories were and remain widely influential, not only on composers of art music, but also on jazz and popular music. His works, composed over a period of nearly sixty years, eschew traditional forms. In addition to electronic music – both with and without live performers – they range from miniatures for musical boxes through works for solo instruments, songs, chamber music, choral and orchestral music, to a cycle of seven full-length operas. His theoretical and other writings comprise ten large volumes. He received numerous prizes and distinctions for his compositions, recordings, and for the scores produced by his publishing company.

The Kyoto Prize in Arts and Philosophy is awarded once a year by the Inamori Foundation for lifetime achievements in the arts and philosophy. The Prize is one of three Kyoto Prize categories; the others are the Kyoto Prize in Advanced Technology and the Kyoto Prize in Basic Sciences. The first Kyoto Prize in Arts and Philosophy was awarded to Olivier Messiaen in 1985, the "greatest composer to have emerged from 20th century France". The Prize is widely regarded as the most prestigious award available in fields not traditionally honored with a Nobel Prize.

Modes of limited transposition are musical modes or scales that fulfill specific criteria relating to their symmetry and the repetition of their interval groups. These scales may be transposed to all twelve notes of the chromatic scale, but at least two of these transpositions must result in the same pitch classes, thus their transpositions are "limited". They were compiled by the French composer Olivier Messiaen, and published in his book La technique de mon langage musical ("The Technique of my Musical Language").
