Musical composition can refer to an original piece of music, either a song or an instrumental music piece, the structure of a musical piece, or the process of creating or writing a new song or piece of music.  People who create new compositions are called composers in classical music.  In popular music and traditional music, the creators of new songs are usually called songwriters; with songs, the person who writes new words for a song is the lyricist.  "Composition" is the act or practice of creating a song or other piece of music.  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 instrumental musicians or singers.  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 her mind and then play, sing and/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. Music for Children is the first release in John Zorn's Music Romance Series and features three Naked City compositions (written at the time of Torture Garden) performed by Zorn with the band Prelapse; a 20-minute composition for wind machines and controlled feedback systems dedicated to Edgar Varese, and a classical chamber music piece for violin, percussion and piano performed by the Abel-Steinberg-Winant Trio framed by a poly-rhythmic etude for percussion and celeste and a lullaby for music box. Beatmapping is the detection of a beat or tempo in music using software.  Beatmapping visually lays out/displays the tempo (speed) of music throughout the entirety or portion of a song or music piece.  This "mapping" is done with software specifically designed for beatmapping. Dub is a genre of music that grew out of reggae in the 1960s, and is commonly considered a subgenre, though it has developed to extend beyond the scope of reggae.  Music in this genre consists predominantly of instrumental remixes of existing recordings and is achieved by significantly manipulating and reshaping the recordings, usually by removing the vocals from an existing music piece, and emphasizing the drum and bass parts (this stripped-down track is sometimes referred to as a riddim).  Other techniques include dynamically adding extensive echo, reverb, panoramic delay, and occasional dubbing of vocal or instrumental snippets from the original version or other works.  It was an early form of popular electronic music.
