A songwriter is a musician who professionally composes musical compositions and writes lyrics for songs. A songwriter can also be called a composer, although the latter term tends to be used mainly for individuals from the classical music genre and film scoring, but is also associated writing and composing the original musical composition or musical bed. A songwriter who mainly writes the lyrics for a song is referred to as a lyricist. The pressure from the music industry to produce popular hits means that song writing is often an activity for which the tasks are distributed between a number of 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 outside publishers.
