Split sheets are an essential safeguard for creators to ensure that they are being properly compensated for the work they contribute to. A split sheet is an agreement that identifies the ownership percentage each producer and/or songwriter has in the song. Songwriter split sheets are an integral part of the music business. A split sheet is a written agreement between the people involved in the creation of music. Oftentimes many producers work on a single track. Typically, each producer would split up the total “producer” percentage (if there's any other than the up front fee). So if the producer's backend is 20% for an indie release and there are 3 producers and they decide to split this equally, then each gets about 6.66%.
