In music, counterpoint is the relationship between two or more musical lines which are harmonically interdependent yet independent in rhythm and melodic contour. It has been most commonly identified in the European classical tradition, strongly developing during the Renaissance and in much of the common practice period, especially in the Baroque period. The term originates from the Latin punctus contra punctum meaning "point against point", i.e. "note against note".
John Milton Cage Jr. was an American composer and music theorist. A pioneer of indeterminacy in music, electroacoustic music, and non-standard use of musical instruments, Cage was one of the leading figures of the post-war avant-garde. Critics have lauded him as one of the most influential composers of the 20th century. He was also instrumental in the development of modern dance, mostly through his association with choreographer Merce Cunningham, who was also Cage's romantic partner for most of their lives.
Henry Dixon Cowell was an American composer, writer, pianist, publisher, teacher and the husband of Sidney Robertson Cowell. Earning a reputation as an extremely controversial performer and eccentric composer, Cowell became a leading figure of American avant-garde music for the first half of the 20th century — his writings and music serving as a great influence to similar artists at the time, including Lou Harrison, George Antheil, and John Cage, among others. He is considered one of America's most important and influential composers.
The Tides of Manaunaun is a short piano piece in B♭ minor by American composer Henry Cowell (1897–1965). It premiered publicly in 1917, serving as a prelude to a theatrical production, The Building of Banba. The Tides of Manaunaun is the best known of Cowell's many tone cluster pieces.
The twelve-tone technique—also known as dodecaphony, twelve-tone serialism, and twelve-note composition—is a method of musical composition first devised by Austrian composer Josef Matthias Hauer, who published his "law of the twelve tones" in 1919. In 1923, Arnold Schoenberg (1874–1951) developed his own, better-known version of 12-tone technique, which became associated with the "Second Viennese School" composers, who were the primary users of the technique in the first decades of its existence. The technique is a means of ensuring that all 12 notes of the chromatic scale are sounded as often as one another in a piece of music while preventing the emphasis of any one note through the use of tone rows, orderings of the 12 pitch classes. All 12 notes are thus given more or less equal importance, and the music avoids being in a key. Over time, the technique increased greatly in popularity and eventually became widely influential on 20th-century composers. Many important composers who had originally not subscribed to or actively opposed the technique, such as Aaron Copland and Igor Stravinsky, eventually adopted it in their music.
Lou Silver Harrison was an American composer, music critic, music theorist, painter, and creator of unique musical instruments. Harrison initially wrote in a dissonant, ultramodernist style similar to his former teacher and contemporary, Henry Cowell, but later moved toward incorporating elements of non-Western cultures into his work. Notable examples include a number of pieces written for Javanese style gamelan instruments, inspired after studying with noted gamelan musician Kanjeng Notoprojo in Indonesia. Harrison would create his own musical ensembles and instruments with his partner, William Colvig, who are now both considered founders of the American gamelan movement and world music; along with composers Harry Partch and Claude Vivier, and ethnomusicologist Colin McPhee.
Elliott Cook Carter Jr. was an American modernist composer. One of the most respected composers of the second half of the 20th century, he combined elements of European modernism and American "ultra-modernism" into a distinctive style with a personal harmonic and rhythmic language, after an early neoclassical phase. His compositions are performed throughout the world, and include orchestral, chamber music, solo instrumental, and vocal works. The recipient of many awards, Carter was twice awarded the Pulitzer Prize.
Henry Dreyfuss Brant was a Canadian-born American composer. An expert orchestrator with a flair for experimentation, many of Brant's works featured spatialization techniques.
Robert Edward "Bob" Brookmeyer was an American jazz valve trombonist, pianist, arranger, and composer. Born in Kansas City, Missouri, Brookmeyer first gained widespread public attention as a member of Gerry Mulligan's quartet from 1954 to 1957. He later worked with Jimmy Giuffre, before rejoining Mulligan's Concert Jazz Band. He garnered 8 Grammy Award nominations during his lifetime.
A tone cluster is a musical chord comprising at least three adjacent tones in a scale. Prototypical tone clusters are based on the chromatic scale and are separated by semitones. For instance, three adjacent piano keys struck simultaneously produce a tone cluster. Variants of the tone cluster include chords comprising adjacent tones separated diatonically, pentatonically, or microtonally. On the piano, such clusters often involve the simultaneous striking of neighboring white or black keys.
In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these.
In musical composition, a sound mass(also sound collective, sound complex, tone shower, sound crowd, or cloud) is the result of compositional techniques, in which, "the importance of individual pitches", is minimized, "in preference for texture, timbre, and dynamics as primary shapers of gesture and impact", obscuring, "the boundary between sound and noise".
Connotations is a classical music composition for symphony orchestra written by American composer Aaron Copland. Commissioned by Leonard Bernstein in 1962 to commemorate the opening of Philharmonic Hall in New York City, United States, this piece marks a departure from Copland's populist period, which began with El Salón México in 1936 and includes the works he is most famous for such as Appalachian Spring, Lincoln Portrait and Rodeo. It represents a return to a more dissonant style of composition in which Copland wrote from the end of his studies with French pedagogue Nadia Boulanger and return from Europe in 1924 until the Great Depression. It was also Copland's first dodecaphonic work for orchestra, a style he had disparaged until he heard the music of French composer Pierre Boulez and adapted the method for himself in his Piano Quartet of 1950. While the composer had produced other orchestral works contemporary to Connotations, it was his first purely symphonic work since his Third Symphony, written in 1947.
Wallingford Constantine Riegger was an American modernist composer and pianist, best known for his orchestral and modern dance music. He was born in Albany, Georgia, but spent most of his career in New York City, helping elevate the status of other American composers such as Charles Ives and Henry Cowell. Riegger is noted for being one of the first American composers to use a form of serialism and the twelve-tone technique.
String piano is a term coined by American composer-theorist Henry Cowell (1897–1965) to collectively describe pianistic extended techniques in which sound is produced by direct manipulation of the strings, instead of or in addition to striking the piano's keys. Pioneered by Cowell in the 1920s, such techniques are now often called upon in the works of avant-garde classical music composers.
American avant-garde composer John Cage (1912–1992) began composing pieces for solo prepared piano around 1938–40. The majority of early works for this instrument were created to accompany dances by Cage's various collaborators, most frequently Merce Cunningham. In response to frequent criticisms of prepared piano, Cage cited numerous predecessors. In the liner notes for the very first recording of his most highly acclaimed work for prepared piano, Sonatas and Interludes, Cage wrote: "Composing for the prepared piano is not a criticism of the instrument. I'm only being practical." This article presents a complete list of Cage's works for prepared piano, with comments on each composition. All of Cage's indeterminate works for unspecified forces can also be performed on or with Prepared Piano.
In musical composition, developing variation is a formal technique in which the variations are produced through the development of existing material. The term was coined by Arnold Schoenberg, twentieth-century composer and inventor of the twelve-tone technique, who believed it was one of the most important compositional principles since around 1750:
Music of the homophonic-melodic style of composition, that is, music with a main theme, accompanied by and based on harmony, produces its material by, as I call it, developing variation. This means that variation of the features of a basic unit produces all the thematic formulations which provide for fluency, contrasts, variety, logic and unity, on the one hand, and character, mood, expression, and every needed differentiation, on the other hand—thus elaborating the idea of the piece.
Inscape is a 1967 musical composition for orchestra by Aaron Copland, approximately twelve to thirteen minutes in length, and commissioned by and dedicated to the New York Philharmonic for its 125th anniversary. Composed using the twelve-tone technique, the piece has been considered less accessible than much of Copland's earlier music. It is named for Gerard Manley Hopkins's term "inscape", invented:
to suggest 'a quasi-mystical illumination, a sudden perception of that deeper pattern, order, and unity which gives meaning to external forms.' This description, it seems to me, applies more truly to the creation of music than to any of the other arts.
American composer Henry Cowell wrote one of his first surviving piano pieces, Dynamic Motion, in 1916. It is known as one of the first pieces in the history of music to utilize violent tone clusters for the keyboard. It requires the performer to use various limbs to play massive secundal chords, and calls for keys to be held down without sounding to extend its dissonant cluster overtones via sympathetic resonance. Some of the clusters outlined in this piece are those written for fists, palms, and forearms. The piece is also noted for its extended use of tuplets, featuring triplets, quintuplets, and sextuplets in the melody line.
Henry Cowell wrote the piano piece The Snows of Fuji-Yama, HC 395, in 1924.
