A split sheet is a written agreement between two or more music creators that identifies each contributor and establishes specific ownership percentages amongst them. These percentages are important because they determine how much each contributor will be paid when income is generated by their music. In general, every song published can be broken down into a writer’s share (lyrics) and a producer’s share (music), with each share being worth 50% of the song. The shares can be broken down even further if there are additional contributors, however, the same creator can contribute to both shares. The final percentages are negotiated and must be agreed upon by all parties involved.
