Copyright gives music creators the following rights:

• Control how their work is used
• Receive compensation for the use of their work
• Be credited as the creator
• Prevent modifications or uses that could compromise their artistic integrity

Copyright protection begins automatically when you create your work.

• No membership in a copyright organization, registration, or formal declaration is required.
• Copyright remains valid throughout the creator’s lifetime, and even extends 70 years after the year of the creator’s death.
• If a work has more than one creator, the copyright of said work remains valid until 70 years has elapsed from the year of the death of the last living creator.
