Who made what, and which rights or agreements follow from that work?
Session lanes
Solo a contribution
Selected lane

Split sheet
Legal names and roles
Work registration data
Being present in the session or performing on the recording does not by itself establish a composition share.
What this means
A recording session can create distinct contributor roles, composition shares, master interests, credits, and contractual obligations.
- Creative contribution, credit, composition ownership, and master ownership are related but not interchangeable.
- Document roles and agreements while the session facts are still clear.
- One person may occupy several roles, and each role should be mapped separately.
