The basic form contains the following: song title, date, project name, followed by a percentage of agreed and awarded fractions, including: percentage of copyright ownership, percentage of publication, percentage of the songwriter and other percentage (optional) that can be added to the bottom of the form in the Additional Information and Notes section. The world of music begins with a creative effort — the song. What will happen next with this song is the music business. Often, the first contact a lyricist has with this business side of music is through the use of a music publishing house. I didn`t create the contract, but I guess it`s written with the idea of a „reversion clause“ that songwriters often want to include in every contract they sign with publishers. The idea is that if this or that writer wishes to withdraw, he can be canceled.
