publisher a negotiated advance against future royalties. The advance amount naturally depends on the writer's bargaining power and on the competition in marketplace, if any. Under a staff writer deal, the writer is paid on a weekly or quarterly basis. An ESWA can be either tied to a record contract, or independent of a record contract. (3) Co-publishing Agreement ("Co-pub"): The co-publishing ("co-pub") deal is perhaps the most common publishing agreement. Under this deal, the songwriter and the music publisher are "co-owners" of the copyrights in the musical compositions. The writer becomes the "co-publisher" (i.e. co-owner) with the music publisher based on an agreed split of the royalties. The songwriter assigns an agreed percentage to the publisher, usually (but not always), a 50/50 split. Thus, the writer conveys _ of the publisher's share to the publisher, but retains all of writer's share. In a typical "75/25 co-pub deal," the writer gets 100% of the songwriter's share, and 50% of the publisher's share, or 75% of the entire copyrights, with the remaining 25% going to the publisher. Thus, when royalties are due and payable, the writer/co-publisher will receive 75% of the income, while the publisher will retain 25%. -To Understand Deeper "In royalty payments, there’s a writers share and a publisher’s share. To make things easy, let’s say each share is worth 100%. So the writer has a pie chart of 100% and the publisher has a pie chart of 100%. If there are multiple writers on the track, then they will split the shares accordingly, 50/50 or 25/25/25/25 if there were 4 writers. After the writers share is calculated, you can calculate the publisher’s share or vice versa. A record label would usually own 100% of an artist’s publishing rights, but if you enter into a co-publishing deal, then the label would only get 50% of your publishing. To break it all down, if an artist negotiated a 50/50 split for publishing, and retains 100% of the writers share, then the artist would get half of the publisher’s share and 100% of the writers share. This would be equal to 75% of the total royalty payment. If you publish your own music, this means you get to keep 100% of your royalties..." (4) Administration Agreement ("Admin"): An administrative agreement takes place between a songwriter/publisher and an independent administrator, or between a writer/publisher and another music publisher. In an "admin deal,"
