Bassline in the context of "Part (music)"

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.

A chord chart (or chart) is a form of musical notation that describes the basic harmonic and rhythmic information for a song or tune. It is the most common form of notation used by professional session musicians playing jazz or popular music. It is intended primarily for a rhythm section (usually consisting of piano, guitar, drums and bass). In these genres the musicians are expected to be able to improvise the individual notes used for the chords (the "voicing") and the appropriate ornamentation, counter melody or bassline.

In some chord charts, the harmony is given as a series of chord symbols above a traditional musical staff. The rhythmic information can be very specific and written using a form of traditional notation, sometimes called rhythmic notation, or it can be completely unspecified using slash notation, allowing the musician to fill the bar with chords or fills any way they see fit (called comping). In Nashville notation the key is left unspecified on the chart by substituting numbers for chord names. This facilitates on-the-spot key changes to songs. Chord charts may also include explicit parts written in modern music notation (such as a musical riff that the song is dependent on for character), lyrics or lyric fragments, and various other information to help the musician compose and play their part.

Orchestration is the study or practice of writing music for an orchestra (or, more loosely, for any musical ensemble, such as a concert band) or of adapting music composed for another medium for an orchestra. Also called "instrumentation", orchestration is the assignment of different instruments to play the different parts (e.g., melody, bassline, etc.) of a musical work. For example, a work for solo piano could be adapted and orchestrated so that an orchestra could perform the piece, or a concert band piece could be orchestrated for a symphony orchestra.

In classical music, composers have historically orchestrated their own music. Only gradually over the course of music history did orchestration come to be regarded as a separate compositional art and profession in itself. In modern classical music, composers almost invariably orchestrate their own work. Two notable exceptions to this are Ravel's orchestration of Mussorgsky's solo piano work Pictures at an Exhibition and Malcolm Arnold's orchestration of William Walton's String Quartet in A minor, producing the latter's Sonata for Strings.

Accompaniment is the musical part which provides the rhythmic and/or harmonic support for the melody or main themes of a song or instrumental piece. There are many different styles and types of accompaniment in different genres and styles of music. In homophonic music, the main accompaniment approach used in popular music, a clear vocal melody is supported by subordinate chords. In popular music and traditional music, the accompaniment parts typically provide the "beat" for the music and outline the chord progression of the song or instrumental piece.

The accompaniment for a vocal melody or instrumental solo can be played by a single musician playing an instrument such as piano, pipe organ, or guitar. While any instrument can in theory be used as an accompaniment instrument, keyboard and guitar-family instruments tend to be used if there is only a single instrument, as these instruments can play chords and basslines simultaneously (chords and a bassline are easier to play simultaneously on keyboard instruments, but a fingerpicking guitarist can play chords and a bassline simultaneously on guitar). A solo singer can accompany themself by playing guitar or piano while they sing, and in some rare cases, a solo singer can even accompany themself just using their voice and body (e.g., Bobby McFerrin).

Blues is a music genre and musical form that originated among African Americans in the Deep South of the United States around the 1860s. Blues has incorporated spirituals, work songs, field hollers, shouts, chants, and rhymed simple narrative ballads from the African-American culture. The blues form is ubiquitous in jazz, rhythm and blues, and rock and roll, and is characterized by the call-and-response pattern, the blues scale, and specific chord progressions, of which the twelve-bar blues is the most common. Blue notes (or "worried notes"), usually thirds, fifths or sevenths flattened in pitch, are also an essential part of the sound. Blues shuffles or walking bass reinforce the trance-like rhythm and form a repetitive effect known as the groove.

Blues music is characterized by its lyrics, bass lines, and instrumentation. Early traditional blues verses consisted of a single line repeated four times. It was only in the first decades of the 20th century that the most common current structure became standard: the AAB pattern, consisting of a line sung over the four first bars, its repetition over the next four, and then a longer concluding line over the last bars. Early blues frequently took the form of a loose narrative, often relating the racial discrimination and other challenges experienced by African Americans.

Baroque music (UK: /bəˈrɒk/ or US: /bəˈroʊk/) refers to the period or dominant style of Western classical music composed from about 1600 to 1750. The Baroque style followed the Renaissance period, and was followed in turn by the Classical period after a short transition (the galant style). The Baroque period is divided into three major phases: early, middle, and late. Overlapping in time, they are conventionally dated from 1580 to 1650, from 1630 to 1700, and from 1680 to 1750. Baroque music forms a major portion of the "classical music" canon, and continues to be widely studied, performed, and listened to. The term "baroque" comes from the Portuguese word barroco, meaning "misshapen pearl". Key composers of the Baroque era include Johann Sebastian Bach, George Frideric Handel, Henry Purcell, Antonio Vivaldi, Georg Philipp Telemann, Domenico Scarlatti, Claudio Monteverdi, Girolamo Frescobaldi, Alessandro Scarlatti, Jean-Baptiste Lully, Jean-Philippe Rameau, Arcangelo Corelli, François Couperin, Heinrich Schütz, Dieterich Buxtehude, and Heinrich Ignaz Franz Biber.

The Baroque saw the formalization of common-practice tonality, an approach to writing music in which a song or piece is written in a particular key; this type of harmony has continued to be used extensively in Western classical and popular music. During the Baroque era, professional musicians were expected to be accomplished improvisers of both solo melodic lines and accompaniment parts. Baroque concerts were typically accompanied by a basso continuo group (comprising chord-playing instrumentalists such as harpsichordists and lute players improvising chords from a figured bass part) while a group of bass instruments—viol, cello, double bass—played the bassline. A characteristic Baroque form was the dance suite. While the pieces in a dance suite were inspired by actual dance music, dance suites were designed purely for listening, not for accompanying dancers.

"Like a Virgin" is a song recorded by American singer Madonna from her second album of the same name. The song was written and composed by Tom Kelly and Billy Steinberg, and it was released as the album's lead single on October 31, 1984. A dance song with two hooks, Madonna sings in a high register while a continuous arrangement of synths are heard along the bassline. The song's lyrics are ambiguous, consisting of hidden innuendos and open to various interpretations.

Upon release, "Like a Virgin" received positive reviews from music critics, who frequently singled out Madonna's vocals. It became her first number-one in the Billboard Hot 100, and topped the charts in Australia and Canada, while reaching the top ten elsewhere; "Like a Virgin" has sold over six million copies worldwide. The accompanying music video was directed by Mary Lambert, and showed Madonna sailing down the canals of Venice in a gondola, as well as roaming around a castle wearing a white wedding dress. The video received positive feedback; authors singled out the expression of Venetian vitality, and noted references to Saint Mark.

Hip-hop culture is an art movement that emerged in New York City, in the borough of The Bronx, primarily within the black community. Hip Hop as an art form and culture has been heavily influenced by both male and female artists. It is characterized by the key elements of rapping, DJing and turntablism, and breakdancing; other elements include graffiti, beatboxing, street entrepreneurship, hip hop language, and hip-hop fashion.Many cite hip-hop's emergence as beginning in August 1973 when brother–sister duo DJ Kool Herc and Cindy Campbell hosted the first documented indoor hip hop party and culture event in the Bronx; Helping to spark the rise of the genre. However many hiphop pioneers and historians contend that Hip Hop did not have just one founding father. The black Spades street gang and Disco King Mario of the Bronxdale Houses are also considered vital in the early origins of hip-hop culture and music. Disco King Mario hosted and organized outdoor hip-hop culture events, and park jams that predated DJ Kool Herc's 1973 indoor hip-hop party. DJ Kool Herc was also among the attendees at Disco King Mario's hip-hop events. Since then hip-hop culture has spread to both urban and suburban communities throughout the United States and subsequently the world. These elements were adapted and developed considerably, particularly as the art forms spread to new continents and merged with local styles in the 1990s and subsequent decades. Even as the movement continues to expand globally and explore myriad styles and art forms, including hip-hop theater and hip hop film, the four foundational elements provide coherence and a strong foundation for hip hop culture.

Hip hop is simultaneously a new and old phenomenon; the importance of sampling tracks, beats, and basslines from old records to the art form means that much of the culture has revolved around the idea of updating classic recordings, attitudes, and experiences for modern audiences. Sampling older culture and reusing it in a new context or a new format is called "flipping" in hip hop culture. Hip hop music follows in the footsteps of earlier African-American-rooted and Latino musical genres such as blues, jazz, rag-time, funk, salsa, and disco to become one of the most practiced genres worldwide.

Disco is a genre of dance music and a subculture that emerged in the late 1960s from the United States' urban nightlife scene, particularly in African-American, Italian-American, Latino and queer communities. Its sound is typified by four-on-the-floor beats, syncopated basslines, string sections, brass and horns, electric pianos, synthesizers, and electric rhythm guitars.

Discothèques as a venue were mostly a French invention, imported to the United States with the opening of Le Club, a members-only restaurant and nightclub located at 416 East 55th Street in Manhattan, by French expatriate Olivier Coquelin, on New Year's Eve 1960.
