Jazz in the context of "Mod (subculture)"

Musical composition can refer to an original piece or work of music, either vocal or instrumental, the structure of a musical piece or to the process of creating or writing a new piece of music. People who create new compositions are called composers. Composers of primarily songs are usually called songwriters; with songs, the person who writes lyrics for a song is the lyricist. In many cultures, including Western classical music, the act of composing typically includes the creation of music notation, such as a sheet music "score", which is then performed by the composer or by other musicians. In popular music and traditional music, songwriting may involve the creation of a basic outline of the song, called the lead sheet, which sets out the melody, lyrics and chord progression. In classical music, orchestration (choosing the instruments of a large music ensemble such as an orchestra which will play the different parts of music, such as the melody, accompaniment, countermelody, bassline and so on) is typically done by the composer, but in musical theatre and in pop music, songwriters may hire an arranger to do the orchestration. In some cases, a pop or traditional songwriter may not use written notation at all and instead compose the song in their mind and then play, sing or record it from memory. In jazz and popular music, notable sound recordings by influential performers are given the weight that written or printed scores play in classical music.

Although a musical composition often uses musical notation and has a single author, this is not always the case. A work of music can have multiple composers, which often occurs in popular music when all members of a band collaborate to write a song or in musical theatre, when one person writes the melodies, a second person writes the lyrics and a third person orchestrates the songs.

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.

New York City has been described as the cultural capital of the world. Its urban culture is reflected in its size and ethnic diversity. As many as 800 languages are spoken in New York, making it the most linguistically diverse city in the world. Many American cultural movements first emerged in the city. Large numbers of Irish, Italian, Jewish, Russian, and eventually African, Latino, and Asian Americans also migrated to New York throughout the 20th century and continuing into the 21st century, significantly influencing the city's culture and image. The city became the center of stand-up comedy in the early 20th century. The city was the top venue for jazz in the 1940s, expressionism in the 1950s and home to hip hop, punk rock, and the Beat Generation. Along with London's West End, New York City is the global center of musical theatre, often referred to as "Broadway" after the major thoroughfare in Manhattan. The Stonewall Inn in Greenwich Village, Lower Manhattan, is a designated U.S. National Historic Landmark and National Monument, as the site of the June 1969 Stonewall riots and the cradle of the modern gay rights movement.

The city is the birthplace of many cultural movements, including the Harlem Renaissance in literature and visual art; abstract expressionism (also known as the New York School) in painting; and hip hop, punk, salsa, freestyle, Tin Pan Alley, certain forms of jazz, and (along with Philadelphia) disco in music. New York has been considered the dance capital of the world. The city is also frequently the setting for novels, movies (see List of films set in New York City), and television programs. New York Fashion Week is one of the world's preeminent fashion events and is afforded extensive coverage by the media.New York has also frequently been ranked the top fashion capital of the world on the annual list compiled by the Global Language Monitor. Artists have been drawn into the city by opportunity, as the city government funds the arts with a larger annual budget than the National Endowment for the Arts, and New York is the center of the global art market, which grew up along with national and international media centers.

Singing is the art of creating music with the voice. It is the oldest form of musical expression, and the human voice can be considered the first musical instrument by some. The definition of singing varies across sources. Some sources define singing as the act of creating musical sounds with the voice. Other common definitions include "the utterance of words or sounds in tuneful succession" or "the production of musical tones by means of the human voice".

A person whose profession (or hobby) is singing is called a singer or a vocalist (in jazz or popular music). Singers perform music (arias, recitatives, songs, etc.) that can be sung with or without accompaniment by musical instruments. Singing is often done in an ensemble of musicians, such as a choir. Singers may perform as soloists or accompanied by anything from a single instrument (as in art songs or some jazz styles) up to a symphony orchestra or big band. Many styles of singing exist throughout the world.

Jazz poetry has been defined as poetry that "demonstrates jazz-like rhythm or the feel of improvisation" and also as poetry that takes jazz music, musicians, or the jazz milieu as its subject, and is designed to be performed. Some critics consider it a distinct genre though others consider the term to be merely descriptive. Jazz poetry has long been something of an "outsider" art form that exists somewhere outside the mainstream, having been conceived in the 1920s by African Americans, maintained in the 1950s by counterculture poets like those of the Beat generation, and adapted in modern times into hip-hop music and live poetry events known as poetry slams.

A film score is original music written specifically to accompany a film or a television program. The score consists of a number of orchestral, instrumental, or choral pieces called cues, which are timed to begin and end at specific points during the film in order to enhance the dramatic narrative and the emotional impact of the scene in question. Scores are written by one or more composers under the guidance of or in collaboration with the film's director or producer and are then most often performed by an ensemble of musicians – usually including an orchestra (most likely a symphony orchestra) or band, instrumental soloists, and choir or vocalists – known as playback singers – and recorded by a sound engineer. The term is less frequently applied to music written for media such as live theatre, television and radio programs, and video games, and that music is typically referred to as either the soundtrack or incidental music.

Film scores encompass an enormous variety of styles of music depending on the nature of the films they accompany. While the majority of scores are orchestral works rooted in Western classical music, many scores are also influenced by jazz, rock, pop, blues, new-age and ambient music, and a wide range of ethnic and world music styles. Since the 1950s, a growing number of scores have also included electronic elements, and many scores written today feature a hybrid of orchestral and electronic instruments.

Rapping (also dropping, rhyming, flowing, spitting, emceeing, or MCing) is an artistic form of vocal delivery and emotive expression that incorporates "rhyme, rhythmic speech, and [commonly] street vernacular". It is usually performed over a backing beat or musical accompaniment. The components of rap include "content" (what is being said, e.g., lyrics), "flow" (rhythm, rhyme), and "delivery" (cadence, tone). Rap differs from spoken-word poetry in that it is usually performed off-time to musical accompaniment. It also differs from singing, which varies in pitch and does not always include words. Because they do not rely on pitch inflection, some rap artists may play with timbre or other vocal qualities. Rap is a primary ingredient of hip-hop music, and so commonly associated with the genre that it is sometimes called "rap music".

Precursors to modern rap music include the West African griot tradition, certain vocal styles of blues and jazz, an African-American insult game called playing the dozens (see Battle rap and Diss), and 1960s African-American poetry. Stemming from the hip-hop cultural movement, rap music originated in the Bronx, New York City, in the early 1970s and became part of popular music later that decade. Rapping developed from the announcements made over the microphone at parties by DJs and MCs, evolving into more complex lyrical performances.

The Royal Academy of Music (RAM) in Westminster, London, England, is one of the oldest music schools in the United Kingdom, founded in 1822 by John Fane and Nicolas-Charles Bochsa. It received its royal charter in 1830 from King George IV with the support of the first Duke of Wellington.

The academy provides undergraduate and postgraduate training across instrumental performance, composition, jazz, musical theatre and opera, and recruits musicians from around the world, with a student community representing more than 50 nationalities. It is committed to lifelong learning, from Junior Academy, which trains musicians up to the age of 18, through Open Academy community music projects, to performances and educational events for all ages.

In a musical composition, a chord progression or harmonic progression (informally chord changes, used as a plural, or simply changes) is a succession of chords. Chord progressions are the foundation of harmony in Western musical tradition from the common practice era of classical music to the 21st century. Chord progressions are the foundation of popular music styles (e.g., pop music, rock music), traditional music, as well as genres such as blues and jazz. In these genres, chord progressions are the defining feature on which melody and rhythm are built.

In tonal music, chord progressions have the function of either establishing or otherwise contradicting a tonality, the technical name for what is commonly understood as the "key" of a song or piece. Chord progressions, such as the extremely common chord progression I-V-vi-IV, are usually expressed by Roman numerals in classical music theory. In many styles of popular and traditional music, chord progressions are expressed using the name and "quality" of the chords. For example, the previously mentioned chord progression, in the key of E♭ major, would be written as E♭ major–B♭ major–C minor–A♭ major in a fake book or lead sheet. In the first chord, E♭ major, the "E♭" indicates that the chord is built on the root note "E♭" and the word "major" indicates that a major chord is built on this "E♭" note.
