Printed Music Publishing Refers To Sheet Music.
A music publisher invests in intellectual property – in other words, songs that are exploited when they are played, performed, copied or heard. One version of exploitation is by sheet music.
Not all music publishers produce their own sheet music. Most will sub-license those rights to third parties who specialize in producing sheet music and songbooks. The companies that still make sheet music and songbooks are known as printed music publishers or print publishers. Most print publishers are also music publishers, but only a few music publishers are also print publishers. You can learn more about the royalties sheet music generates here.
