Jazz fusion in the context of "Frank Zappa"

Musical improvisation (also known as musical extemporization) is the creative activity of immediate ("in the moment") musical composition, which combines performance with communication of emotions and instrumental technique as well as spontaneous response to other musicians. Sometimes musical ideas in improvisation are spontaneous, but may be based on chord changes in classical music and many other kinds of music. One definition is a "performance given extempore without planning or preparation". Another definition is to "play or sing (music) extemporaneously, by inventing variations on a melody or creating new melodies, rhythms and harmonies". Encyclopædia Britannica defines it as "the extemporaneous composition or free performance of a musical passage, usually in a manner conforming to certain stylistic norms but unfettered by the prescriptive features of a specific musical text." Improvisation is often done within (or based on) a pre-existing harmonic framework or chord progression. Improvisation is a major part of some types of 20th-century music, such as blues, rock music, jazz, and jazz fusion, in which instrumental performers improvise solos, melody lines and accompaniment parts.

Throughout the eras of the Western art music tradition, including the Medieval, Renaissance, Baroque, Classical, and Romantic periods, improvisation was a valued skill. J. S. Bach, Handel, Mozart, Beethoven, Chopin, Liszt, and many other famous composers and musicians were known especially for their improvisational skills. Improvisation might have played an important role in the monophonic period. The earliest treatises on polyphony, such as the Musica enchiriadis (ninth century), indicate that added parts were improvised for centuries before the first notated examples. However, it was only in the fifteenth century that theorists began making a hard distinction between improvised and written music.

The violin, sometimes referred to as a fiddle, is a wooden chordophone, and is the smallest, and thus highest-pitched instrument (soprano) in regular use in the violin family. Smaller violin-type instruments exist, including the violino piccolo and the pochette, but these are virtually unused. Most violins have a hollow wooden body, and commonly have four strings (sometimes five), usually tuned in perfect fifths with notes G3, D4, A4, E5, and are most commonly played by drawing a bow across the strings. The violin can also be played by plucking the strings with the fingers (pizzicato) and, in specialized cases, by striking the strings with the wooden side of the bow (col legno).

Violins are important instruments in a wide variety of musical genres. They are most prominent in the Western classical tradition, both in ensembles (from chamber music to orchestras) and as solo instruments. Violins are also important in many varieties of folk music, including country music, bluegrass music, and in jazz. Electric violins with solid bodies and piezoelectric pickups are used in some forms of rock music and jazz fusion, with the pickups plugged into instrument amplifiers and speakers to produce sound. The violin has come to be incorporated in many non-Western music cultures, including Indian music and Iranian music. The name fiddle is often used regardless of the type of music played on it.

Robert Keith McFerrin Jr. (born March 11, 1950) is an American singer, songwriter, and conductor. His vocal techniques include singing fluidly but with quick and considerable jumps in pitch—for example, sustaining a melody while also rapidly alternating with arpeggios and harmonies—as well as scat singing, polyphonic overtone singing, and improvisational vocal percussion. He performs and records regularly as an unaccompanied solo vocal artist. He has frequently collaborated with other artists from both the jazz and classical scenes.

McFerrin's song "Don't Worry, Be Happy" is the only acapella track to ever reach No. 1 in the US, which it reached in 1988 and additionally won Song of the Year and Record of the Year honors at the 1989 Grammy Awards. McFerrin has also worked in collaboration with jazz fusion instrumentalists including pianists Chick Corea (of Return to Forever), Herbie Hancock (of The Headhunters), and Joe Zawinul (of Weather Report), drummer Tony Williams, and cellist Yo-Yo Ma.

A guitar solo is a melodic passage, instrumental section, or entire piece of music, pre-written (or improvised) to be played on a classical, electric, or acoustic guitar. In 20th and 21st century traditional music and popular music such as blues, swing, jazz, jazz fusion, rock and heavy metal, guitar solos often contain virtuoso techniques and varying degrees of improvisation. Guitar solos on classical guitar, which are typically written in musical notation, are also used in classical music forms such as chamber music and concertos.

Guitar solos range from unaccompanied works for a single guitar to compositions with accompaniment from a few other instruments or a large ensemble. The accompaniment musicians for a guitar solo can range from a small ensemble such as a jazz quartet or a rock band, to a large ensemble such as an orchestra or big band. Unaccompanied acoustic guitar music is found in folk and classical music dating as far back as the instrument's first use in western music, the use of an acoustic guitar as a solo voice within an ensemble dates back at least to the Baroque concerto.

Neo soul (sometimes called progressive soul) is a genre of popular music. As a term, it was coined by music industry entrepreneur Kedar Massenburg during the late 1990s to market and describe the style of music that emerged from soul and contemporary R&B. Evolving from soul music, neo soul is distinguished by a less conventional sound than its contemporary R&B counterpart, with elements ranging from funk, jazz fusion, hip hop and rock. It has been noted by music writers for its conscious lyrics.

Neo soul developed during the 1980s and early 1990s, by Black-Americans in the United States, as a soul revival movement. It earned mainstream success during the late 1990s, with the commercial and critical breakthroughs of several artists, including D'Angelo, Maxwell, Erykah Badu, and Lauryn Hill. Their music was marketed as an alternative to the producer-driven, digitally approached R&B of the time, although many of them were ambivalent about the term.

Progressive soul (often shortened to prog-soul; also called black prog, black rock, and progressive R&B) is a type of African-American music that uses a progressive approach, particularly in the context of the soul and funk genres. It developed in the late 1960s and early 1970s through the recordings of innovative black musicians who pushed the structural and stylistic boundaries of those genres. Among their influences were musical forms that arose from rhythm and blues music's transformation into rock, such as Motown, progressive rock, psychedelic soul, and jazz fusion.

Progressive soul music can feature an eclectic range of influences, from both African and European sources. Musical characteristics commonly found in works of the genre are traditional R&B melodies, complex vocal patterns, rhythmically unified extended composition, ambitious rock guitar, and instrumental techniques borrowed from jazz. Prog-soul artists often write songs around album-oriented concepts and socially conscious topics based in the African-American experience, left-wing politics, and bohemianism, sometimes employing thematic devices from Afrofuturism and science fiction. Their lyrics, while challenging, can also be marked by irony and humor.

Jean-Luc Ponty (born 29 September 1942) is a French jazz and jazz fusion violinist and composer. He is considered a pioneer of jazz-rock, particularly for his use of the electric violin starting in the 1970s. He rose to prominence for his collaborations with popular musical artists Frank Zappa and Elton John. In addition to his solo work, he has performed with symphony orchestras in France, the United States, Canada, and Japan.

Herbert Jeffrey Hancock (born April 12, 1940) is an American jazz musician, bandleader, and composer. He started his career with trumpeter Donald Byrd's group. Hancock soon joined the Miles Davis Quintet, where he helped to redefine the role of a jazz rhythm section and was one of the primary architects of the post-bop sound. In the 1970s, he experimented with jazz fusion, funk, and electro styles using a wide array of synthesizers and electronics. It was during this time that he released one of his best-known and most influential albums, Head Hunters.

Hancock's best-known compositions include "Cantaloupe Island", "Watermelon Man", "Maiden Voyage", and "Chameleon", all of which are jazz standards. During the 1980s, he had a hit single with the electronic instrumental "Rockit", a collaboration with bassist/producer Bill Laswell. Hancock has won an Academy Award and 14 Grammy Awards, including Album of the Year for his 2007 album River: The Joni Letters, a tribute to his friend Joni Mitchell. In 2024, Neil McCormick of The Daily Telegraph ranked Hancock as the greatest keyboard player of all time. In 2025, he received the Polar Music Prize.
