John Coolidge Adams (born February 15, 1947) is an American composer and conductor. Among the most regularly performed composers of contemporary classical music, he is particularly noted for his operas, many of which center around historical events. Apart from opera, his oeuvre includes orchestral, concertante, vocal, choral, chamber, electroacoustic, and piano music. Born in Worcester, Massachusetts, Adams grew up in a musical family and was exposed to classical music, jazz, musical theatre, and rock music. He attended Harvard University, studying with Leon Kirchner, Roger Sessions, and David Del Tredici, among others. His earliest work was aligned with modernist music, but he began to disagree with its tenets upon reading John Cage's Silence: Lectures and Writings. Teaching at the San Francisco Conservatory of Music, Adams developed a minimalist aesthetic first fully realized in Phrygian Gates (1977) and later in the string septet Shaker Loops. Adams became increasingly active in San Francisco's contemporary music scene, and his orchestral works Harmonium (1980–1981) and Harmonielehre (1985) first gained him national attention. Other popular works from this time include the fanfare Short Ride in a Fast Machine (1986) and the orchestral work El Dorado (1991). Adams's first opera was Nixon in China (1987), which recounts Richard Nixon's 1972 visit to China and was the first of many collaborations with theatre director Peter Sellars. Though the work's reception was initially mixed, it has become increasingly respected since its premiere, receiving performances worldwide. Begun soon after Nixon in China, the opera The Death of Klinghoffer (1991) was based on the Palestinian Liberation Front's 1985 hijacking and murder of Leon Klinghoffer and incited considerable controversy for its subject matter. His next notable works include a Chamber Symphony (1992), a Violin Concerto (1993), the opera-oratorio El Niño (2000), the orchestral piece My Father Knew Charles Ives (2003), and the six-string electric violin concerto The Dharma at Big Sur (2003). Adams won a Pulitzer Prize for Music for On the Transmigration of Souls (2002), a piece for orchestra and chorus commemorating the victims of the September 11, 2001 attacks. Continuing with historical subjects, Adams wrote the opera Doctor Atomic (2005), based on J. Robert Oppenheimer, the Manhattan Project, and the building of the first atomic bomb. Later operas include A Flowering Tree (2006), Girls of the Golden West (2017), and Antony and Cleopatra (2022). In many ways, Adams's music is developed from the minimalist tradition of Steve Reich and Philip Glass, but he tends to more readily engage in the immense orchestral textures and climaxes of late Romanticism in the vein of Wagner and Mahler. His style is to a considerable extent a reaction against the modernism and serialism of the Second Viennese and Darmstadt Schools. In addition to the Pulitzer, Adams has received the Erasmus Prize, a Grawemeyer Award, five Grammy Awards, the Harvard Arts Medal, France's Ordre des Arts et des Lettres, and six honorary doctorates.

Chamber Symphony is a 1992 composition for a 15-member chamber orchestra by American composer John Adams, inspired by Arnold Schoenberg's Chamber Symphony No. 1, Op. 9. It is a three-movement work that takes about 23 minutes to perform.

Doctor Atomic is an opera by the contemporary American composer John Adams, with a libretto by Peter Sellars. It premiered at the San Francisco Opera on October 1, 2005. The work focuses on how leading figures at Los Alamos dealt with the great stress and anxiety of preparing for the test of the first atomic bomb, the "Trinity" test. In 2007, a documentary was made by Jon H. Else about the creation of the opera and collaboration between Adams and Sellars, titled Wonders Are Many.

Grand Pianola Music is a minimalist composition by the American composer John Adams written in 1981. It was premiered on February 26, 1982, by the San Francisco Symphony in the Japan Center in San Francisco as part of a series called "New and Unusual Music". The pianists Robin Sutherland and Julie Steinberg, sopranos Marlene Rozofsky and Eileen Williams, and alto Elizabeth Anker performed with the orchestra. The composer conducted.

Harmonielehre is a 40-minute orchestral composition by the American composer John Adams, composed in 1985. In his memoir, Adams wrote that the piece "was a statement of belief in the power of tonality at a time when I was uncertain about its future" and that it was "a one-of-kind [sic] once-only essay in the wedding of fin-de-siècle chromatic harmony with the rhythmic and formal procedures of Minimalism". The composition's title, German for "study of harmony", is a reference to Arnold Schoenberg's 1911 music theory textbook of the same name, a study of tonal harmony. Other theory texts titled Harmonielehre include those by Heinrich Schenker (1906) and Hugo Riemann (1893). Adams has said that the piece was inspired by a dream he had in which he was driving across the San Francisco–Oakland Bay Bridge and saw an oil tanker on the surface of the water abruptly turn upright and take off like a Saturn V rocket. This dream and the composition of Harmonielehre shortly thereafter ended a writer's block Adams had been experiencing for 18 months.

Lollapalooza is a short piece composed by American minimalist composer John Adams in 1995. The piece is based on the rhythm of the word 'Lollapalooza'. It was composed as a fortieth birthday present to the British conductor Simon Rattle, with whom Adams has worked in the past. It was first performed November 10, 1995 by the City of Birmingham Symphony Orchestra, with Rattle conducting.

Must the Devil Have All the Good Tunes? is a piano concerto by the American composer John Adams. Its title is taken from a saying attributed to Martin Luther. The work was premiered on March 7, 2019 by Yuja Wang and the Los Angeles Philharmonic, conducted by Gustavo Dudamel. A recording, made by Wang, Dudamel, and the Los Angeles Philharmonic in November 2019, was released digitally by Deutsche Grammophon on April 17, 2020. The piece is Adams' third piano concerto, after Eros Piano (1989) and Century Rolls (1997).

Short Ride in a Fast Machine is a 1986 orchestral work by John Adams. Adams applies the description "fanfare for orchestra" to this work and to the earlier Tromba Lontana (1986). The former is also known as Fanfare for Great Woods because it was commissioned for the Great Woods Festival of the Pittsburgh Symphony Orchestra. As a commentary on the title, Adams inquires, "You know how it is when someone asks you to ride in a terrific sports car, and then you wish you hadn't?" The work is an example of Adams's postminimal style, which is utilized in other works like Phrygian Gates, Shaker Loops, and Nixon in China. This style derives from minimalism as defined by the works of Steve Reich, Terry Riley, and Philip Glass, although it proceeds to "make use of minimalist techniques in more dramatic settings." A typical performance of Short Ride lasts about four and a half minutes.

The Chairman Dances is a 1985 composition by John Adams, subtitled Foxtrot for Orchestra and lasting about 13 minutes. A commission from the Milwaukee Symphony Orchestra, it has several dance-like tunes and has been described by Adams as an "outtake" from Act III of the opera he was working on at the time, Nixon in China. The word "Dances" in the title is a verb, not a noun. In the opera, the music depicts Madame Mao gate-crashing a presidential banquet, hanging paper lanterns, and performing a seductive dance; Chairman Mao descends from his portrait, and the two dance a foxtrot, back in time together. The piece ends with the sound of a gramophone winding down. The Chairman Dances was used in the Civilization IV and I Am Love soundtracks.

The Dharma at Big Sur is a composition for solo electric violin and orchestra by the American composer John Adams. The piece calls for some instruments (harps, piano, samplers) to use just intonation, a tuning system in which intervals sound pure, rather than equal temperament, the common Western tuning system in which all intervals except the octave are slightly impure. The piece was composed in 2003 for the opening of Walt Disney Concert Hall in Los Angeles and was conducted by Esa-Pekka Salonen. The electric violin solo was written for violinist Tracy Silverman.

The Violin Concerto by the American composer John Adams was written in 1993. Its premiere was on January 19, 1994, by Jorja Fleezanis with the Minnesota Orchestra, conducted by Edo de Waart, at the Ordway Music Theater, Saint Paul, Minnesota. The piece was co-commissioned by the New York City Ballet, leading to a strong sense of rhythm throughout the entire work. For it, Adams received the University of Louisville Grawemeyer Award for Music Composition. A typical performance lasts around 35 minutes. The Violin Concerto has been described as "the most original approach to the genre since the Alban Berg Concerto".
