Sheet music publishing is the process of producing and distributing written music for various instruments and voices. This includes creating notations that musicians can read and perform. Publishers often work with composers to ensure their music is accurately represented and accessible to performers. The published sheet music can be sold in physical formats, like books, or digitally through online platforms. Music publishers also handle licensing, allowing others to perform or record the music legally. This helps protect the rights of composers and ensures they receive royalties for their work.
