Rhythm sectionA rhythm section is a group of musicians within a music ensemble or band that provides the underlying rhythm, harmony and pulse of the accompaniment, providing a rhythmic and harmonic reference and "beat" for the rest of the band. The rhythm section is often contrasted with the roles of other musicians in the band, such as the lead guitarist or lead vocals whose primary job is to carry the melody. The core elements of the rhythm section are usually the drum kit and bass. The drums and bass provide the basic pulse and groove of a song.
Free jazzFree jazz or Free Form in the early- to mid-1970s is a style of avant-garde jazz or an experimental approach to jazz improvisation that developed in the late 1950s and early 1960s when musicians attempted to change or break down jazz conventions, such as regular tempos, tones, and chord changes. Musicians during this period believed that the bebop and modal jazz that had been played before them was too limiting, and became preoccupied with creating something new.
Music genreA music genre is a conventional category that identifies some pieces of music as belonging to a shared tradition or set of conventions. It is to be distinguished from musical form and musical style, although in practice these terms are sometimes used interchangeably. Music can be divided into genres in varying ways, such as popular music and art music, or religious music and secular music. The artistic nature of music means that these classifications are often subjective and controversial, and some genres may overlap.
Musical improvisationMusical 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".
Modal jazzModal jazz is jazz that makes use of musical modes, often modulating among them to accompany the chords instead of relying on one tonal center used across the piece. Although precedents exist, modal jazz was crystallized as a theory by composer George Russell in his 1953 book Lydian Chromatic Concept of Tonal Organization. Though exerting influence to the present, modal jazz was most popular in the 1950s and 1960s, as evidenced by the success of Miles Davis's 1958 composition "Milestones" and 1959 album Kind of Blue, and John Coltrane's quartet from 1960 to 1965; both artists were directly inspired by Russell.
Sun RaLe Sony'r Ra (born Herman Poole Blount, May 22, 1914 – May 30, 1993), better known as Sun Ra, was an American jazz composer, bandleader, piano and synthesizer player, and poet known for his experimental music, "cosmic" philosophy, prolific output, and theatrical performances. For much of his career, Ra led "The Arkestra", an ensemble with an ever-changing name and flexible line-up. Born and raised in Alabama, Blount became involved in the Chicago jazz scene during the late 1940s.
Experimental rockExperimental rock, also called avant-rock, is a subgenre of rock music that pushes the boundaries of common composition and performance technique or which experiments with the basic elements of the genre. Artists aim to liberate and innovate, with some of the genre's distinguishing characteristics being improvisational performances, avant-garde influences, odd instrumentation, opaque lyrics (or instrumentals), unorthodox structures and rhythms, and an underlying rejection of commercial aspirations.
Rhapsody in BlueRhapsody in Blue is a 1924 musical composition written by George Gershwin for solo piano and jazz band, which combines elements of classical music with jazz-influenced effects. Commissioned by bandleader Paul Whiteman, the work premiered in a concert titled "An Experiment in Modern Music" on February 12, 1924, in Aeolian Hall, New York City. Whiteman's band performed the rhapsody with Gershwin playing the piano. Whiteman's arranger Ferde Grofé orchestrated the rhapsody several times including the 1924 original scoring, the 1926 pit orchestra scoring, and the 1942 symphonic scoring.
SaxophoneThe saxophone (often referred to colloquially as the sax) is a type of single-reed woodwind instrument with a conical body, usually made of brass. As with all single-reed instruments, sound is produced when a reed on a mouthpiece vibrates to produce a sound wave inside the instrument's body. The pitch is controlled by opening and closing holes in the body to change the effective length of the tube. The holes are closed by leather pads attached to keys operated by the player.
RiffA riff is a repeated chord progression or refrain in music (also known as an ostinato figure in classical music); it is a pattern, or melody, often played by the rhythm section instruments or solo instrument, that forms the basis or accompaniment of a musical composition. Though riffs are most often found in rock music, heavy metal music, Latin, funk, and jazz, classical music is also sometimes based on a riff, such as Ravel's Boléro.
