Composer in the context of "Acousmatic sound"

Media, or mediums, are the core types of material (or related other tools) used by an artist, composer, designer, etc. to create a work of art. For example, a visual artist may broadly use the media of painting or sculpting, which themselves have more specific media within them, such as watercolor paints or marble.

The following is a list of artistic categories and the media used within each category:

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.

Opera is a form of Western theatre in which music is a fundamental component and dramatic roles are taken by singers. Such a "work" (the literal translation of the Italian word "opera") is typically a collaboration between a composer and a librettist and incorporates a number of the performing arts, such as acting, scenery, costume, and sometimes dance or ballet. The performance is typically given in an opera house, accompanied by an orchestra or smaller musical ensemble, which since the early 19th century has been led by a conductor. Although musical theatre is closely related to opera, the two are considered to be distinct from one another.

Opera is a key part of Western classical music, and Italian tradition in particular. Originally understood as an entirely sung piece, in contrast to a play with songs, opera has come to include numerous genres, including some that include spoken dialogue such as Singspiel and Opéra comique. In traditional number opera, singers employ two styles of singing: recitative, a speech-inflected style, and self-contained arias. The 19th century saw the rise of the continuous music drama.

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.

A lyricist is a writer who writes lyrics (the spoken words), as opposed to a composer, who writes the song's music which may include but not limited to the melody, harmony, arrangement and accompaniment.

A troubadour (English: /ˈtruːbədɔːr, -dʊər/, French: [tʁubaduʁ] ; Occitan: trobador [tɾuβaˈðu] ) was a composer and performer of Old Occitan lyric poetry during the High Middle Ages (1100–1350). Since the word troubadour is etymologically masculine, a female equivalent is usually called a trobairitz.

The troubadour school or tradition began in the late 11th century in Occitania, but it subsequently spread to the Italian and Iberian Peninsulas. Under the influence of the troubadours, related movements sprang up throughout Europe: the Minnesang in Germany, trovadorismo in Galicia and Portugal, and that of the trouvères in northern France. Dante Alighieri in his De vulgari eloquentia defined the troubadour lyric as fictio rethorica musicaque poita: rhetorical, musical, and poetical fiction. After the "classical" period around the turn of the 13th century and a mid-century resurgence, the art of the troubadours declined in the 14th century and around the time of the Black Death (1348) and since died out.

A songwriter is a person who creates musical compositions or writes lyrics for songs, or both. The writer of the music for a song can be called a composer, although this term tends to be used mainly in the classical music genre and film scoring. A songwriter who mainly writes the lyrics for a song is referred to as a lyricist. Pressure from the music industry to produce popular hits means that songwriting is often a collaborative process with tasks shared among multiple people. For example, a songwriter who excels at writing lyrics might be paired with a songwriter with the task of creating original melodies. Pop songs may be composed by group members from the band or by staff writers – songwriters directly employed by music publishers. Some songwriters serve as their own music publishers, while others have external publishers.

The old-style apprenticeship approach to learning how to write songs is being supplemented by university degrees, college diplomas and "rock schools". Knowledge of modern music technology (sequencers, synthesizers, computer sound editing), songwriting elements and business skills are significant for modern songwriters. Several music colleges offer songwriting diplomas and degrees with music business modules. Since songwriting and publishing royalties can be substantial sources of income, particularly if a song becomes a hit record; legally, in the US, songs written after 1934 may be copied only by the authors. The legal power to grant these permissions may be bought, sold or transferred. This is governed by international copyright law.

A musician is someone who composes, conducts, or performs music. According to the United States Employment Service, "musician" is a general term used to designate a person who follows music as a profession. Musicians include songwriters, who write both music and lyrics for songs; conductors, who direct a musical performance; and performers, who perform for an audience. A music performer is generally either a singer (also known as a vocalist), who provides vocals, or an instrumentalist, who plays a musical instrument. Musicians may perform on their own or as part of a group, band or orchestra.

Musicians may specialize in a musical genre, although many perform across a variety of styles and often blend or cross genres. Their musical output is influenced by a range of factors, including culture, skill set, life experience, education, and creative preferences. A musician who records and releases music is often referred to as a recording artist; while a musician who primarily writes and records art music, media soundtracks , and scores—including for films, theatrical stage productions, and video games—or classical music is usually called a composer. A music producer, while not a musician outright, may themselves be a musician. A conductor, by way of gestures, leads and provides live direction for, or conducts, an ensemble, typically an orchestra or choral group.

In legal discourse, an author is the creator of an original work that has been published, whether that work exists in written, graphic, visual, or recorded form. The act of creating such a work is called authorship, which means a sculptor, painter, or composer is considered the author of their respective sculptures, paintings, or musical compositions. Although in common usage, the term "author" is often associated specifically with the writer of a book, article, play, or other written work. In cases involving a work for hire, the employer or commissioning party is legally considered the author of the work, even if it was created by someone else.

Typically, the first owner of a copyright is the creator of the copyrighted work, i.e., the author. If more than one person created the work, then joint authorship has taken place. Copyright law differs around the world. The United States Copyright Office, for example, defines copyright as "a form of protection provided by the laws of the United States (title 17, U.S. Code) to authors of 'original works of authorship.'"
