The music business, like selling records and becoming a music star, is a tiny part of the industry whereas the business of music extends to a wide range of occupations, from writing music for commercials to engineering in a recording studio to teaching. And while becoming a star is so rare that it is unachievable for the vast majority of musicians, there are many opportunities to make a living in the business of music. It might not be a regular nine-to-five job, but it is much like other entrepreneurial ventures.
