Music Publishing World

I Plan On Recording An Album For A Hip-hop Music Group In My Home Studio...and I Will Have Contracts Ready For Them For Copyrights And Licensing. I Have Some Premade Contracts Which I Am Typing Up To My Own Expectations..but They Refer To The "Publisher" Alot. As I Am The One Making Tracks For These Groups....I Don't Own A Publishing Company. Would I Still Be Considered The Publisher?
