Bach in the context of "Leipzig University"

A fricative is a consonant produced by forcing air through a narrow channel made by placing two articulators close together. These may be the lower lip against the upper teeth, in the case of [f]; the back of the tongue against the soft palate in the case of German [x] (the final consonant of Bach); or the side of the tongue against the molars, in the case of Welsh [ɬ] (appearing twice in the name Llanelli). This turbulent airflow is called frication.

A particular subset of fricatives are the sibilants. When forming a sibilant, one still is forcing air through a narrow channel, but in addition, the tongue is curled lengthwise to direct the air over the edge of the teeth. English [s], [z], [ʃ], and [ʒ] are examples of sibilants.

An allemande (French pronunciation: [almɑ̃d] , "German (dance)"; also allemanda, almain(e), or alman(d)) is a Renaissance and Baroque dance, and one of the most common instrumental dance styles in Baroque music, with examples by Couperin, Purcell, Bach and Handel. It is often the first movement of a Baroque suite of dances, paired with a subsequent courante, though it is sometimes preceded by an introduction or prelude. Along with the waltz and ländler, the allemande was sometimes referred to by the generic term German Dance in publications during the late 18th and early 19th centuries.

A quite different, later, Allemande, named as such in the time of Mozart and Beethoven, still survives in Germany and Switzerland and is a lively triple-time social dance related to the waltz and the Ländler.

Harry Partch (June 24, 1901 – September 3, 1974) was an American composer, music theorist, and creator of unique musical instruments. He composed using scales of unequal intervals in just intonation, and was one of the first 20th-century composers in the West to work systematically with microtonal scales, alongside Lou Harrison. He built his own instruments in these tunings on which to play his compositions, and described the method behind his theory and practice in his book Genesis of a Music (1947).

Partch composed with scales dividing the octave into 43 unequal tones derived from the natural harmonic series; these scales allowed for more tones of smaller intervals than in standard Western tuning, which uses twelve equal intervals to the octave. To play his music, Partch built many unique instruments, with such names as the Chromelodeon, the Quadrangularis Reversum, and the Zymo-Xyl. Partch described his music as "corporeal" (emphasizing its physical/visceral elements), and distinguished it from abstract music, which he perceived as the dominant trend in Western music since the time of J.S. Bach, whose seminal book of preludes and fugues called The Well-tempered Clavier (in German, Das wohltemperierte Klavier) is often cited as the pivot point beyond which older mean-tone and ancient just intonation tunings were abandoned (in the late-18th century) and the then-future of Western Classical (and popular) instruments were (and most are still) based, for exploitation of all 24 theoretical key signatures. Partch's earliest compositions were small-scale pieces to be intoned with simple folkloric-like string instrumental backing; his later works were large-scale (like a fusion of theater and music decidedly related to but quite apart from Wagnerian opera), they were integrated theater productions in which he expected each of the performers to sing, dance, speak, and play instruments in a "corporeal apotheosis". Ancient Greek theatre and Japanese Noh and kabuki heavily influenced Harry Partch's music theatre.

Paul Hindemith (/ˈpaʊl ˈhɪndəmɪt/ POWL HIN-də-mit; German: [ˌpaʊ̯l ˈhɪndəmɪt] ; 16 November 1895 – 28 December 1963) was a German and American composer, music theorist, teacher, violist and conductor. He founded the Amar Quartet in 1921, touring extensively in Europe. As a composer, he became a major advocate of the Neue Sachlichkeit (New Objectivity) style of music in the 1920s, with compositions such as Kammermusik, including works with viola and viola d'amore as solo instruments in a neo-Bachian spirit. Other notable compositions include his song cycle Das Marienleben (1923), his oratorio Das Unaufhörliche (1931), Der Schwanendreher for viola and orchestra (1935), the opera Mathis der Maler (1938) and the symphony Mathis der Maler (1934), the Symphonic Metamorphosis of Themes by Carl Maria von Weber (1943), and the oratorio When Lilacs Last in the Dooryard Bloom'd (1946), a requiem based on Walt Whitman's poem. Hindemith and his wife emigrated to Switzerland and the United States ahead of World War II, after worsening difficulties with the Nazi German regime. In his later years, he conducted and recorded much of his own music.

Most of Hindemith's compositions are anchored by a foundational tone, and use musical forms and counterpoint and cadences typical of the Baroque and Classical traditions. His harmonic language is more modern, freely using all 12 notes of the chromatic scale within his tonal framework, as detailed in his three-volume treatise, The Craft of Musical Composition.

George Henry Crumb Jr. (24 October 1929 – 6 February 2022) was an American composer of avant-garde contemporary classical music. Early in his life he rejected the widespread modernist usage of serialism, developing a highly personal musical language which "range[s] in mood from peaceful to nightmarish". Crumb's compositions are known for pushing the limits of technical prowess by way of frequent use of extended techniques. The unusual timbres he employs evoke a surrealist atmosphere which portray emotions of considerable intensity with vast and sometimes haunting soundscapes. His few large-scale works include Echoes of Time and the River (1967), which won the 1968 Pulitzer Prize for Music, and Star-Child (1977), which won the 2001 Grammy Award for Best Contemporary Classical Composition; however, his output consists of mostly music for chamber ensembles or solo instrumentalists. Among his best known compositions are Black Angels (1970), a striking commentary on the Vietnam War for electric string quartet; Ancient Voices of Children (1970) for a mixed chamber ensemble; and Vox Balaenae (1971), a musical evocation of the humpback whale, for electric flute, electric cello, and amplified piano.

Born to a musical family, Crumb was acquainted with classical music at an early age and his affinity for Classical and Romantic composers in particular would stay throughout his life. He was especially influenced by composers such as Mahler, Debussy and Bartók; Crumb wrote his four-volume piano set Makrokosmos (1972–1979) in response to Bartók's earlier piano set Mikrokosmos. His compositions often contain musical quotations from wide range of composers including Bach, Chopin, Schubert, Strauss, and the jazz pianist and composer Thelonious Monk. The use of pastiche is also found in his music, as is text by Federico García Lorca, whose poetry Crumb set eleven times. Elements of theatricality appear in numerous compositions, inspiring choreographies from contemporary dance groups. To convey his unorthodox and complex musical style, Crumb's musical scores are facsimile manuscripts, using special notation "distinguished by astonishing clarity, precision and elegance, and by arresting graphic symbols in which staves are bent into arches, circles and other pictorial devices." Among his students were the composers Osvaldo Golijov, Jennifer Higdon, Christopher Rouse and Melinda Wagner.

When describing popular music artists, honorific nicknames are used, most often in the media or by fans, to indicate the significance of an artist, and are often religious, familial, or most frequently royal and aristocratic titles, used metaphorically. Honorific nicknames were used in classical music in Europe even in the early 19th century, with figures such as Mozart being called "The father of modern piano music" and Bach "The father of modern music". They were also particularly prominent in African-American culture in the post-Civil War era, perhaps as a means of conferring status that had been negated by slavery, and as a result entered early jazz and blues music, including figures such as Duke Ellington and Count Basie.

In U.S. culture, despite its republican constitution and ideology, royalist honorific nicknames have been used to describe leading figures in various areas of activity, such as industry, commerce, sports, and the media; father or mother have been used for innovators, and royal titles such as king and queen for dominant figures in a field. In the 1930s and 1940s, as jazz and swing music were gaining popularity, it was the more commercially successful white artists Paul Whiteman and Benny Goodman who became known as "the King of Jazz" and "the King of Swing" respectively, despite there being more highly regarded contemporary African-American artists.
