What is a song? A song is a musical composition with a melody. Most songs have lyrics that can be sung to the tune of the melody.
If you write song lyrics that have a melody (words with a tune you can sing), you are a songwriter. If you create melodies or tunes with no lyrics, you are a music composer. If you write poems or lyrics with no musical melody, you are a lyricist. Lyricists often collaborate with music composers to become a songwriting team.
Collaboration:
The joint effort of two or more persons in the creation of a musical composition.
If you write lyrics (words with no melody) and need a music composer, collaboration is available at thewordking.com.
