composed musical work

Scherzo in A flat by the Russian Romantic era composer Alexander Borodin (1833–1887) Play Jazz, rock and pop songwriters typically write out newly composed songs in a lead sheet, which notates the melody, the chord progression and the tempo or style of the song (e.g., "slow blues"). Jazz and rock genre musicians may memorize the melodies for a new song, which means that they only need to provide a chord chart to guide improvising musicians. Play

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 music. People who create 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 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.
