I've been talking with a new potential member about setting up an agreement for me to help him. He is a singer songwriter writing mostly pop music. He writes lyrics, music, and performs all the tracks (instruments and vocals). My role so far would be to fine tune production, arrangement, replace instruments at times with my own, mix and master the songs. And re-do mixes when necessary based on screener comments and other feedback. He would rather not pay for the services but give me a royalty portion instead. Given that my work has no advance and is solely based on a possible future payout;
What would be a fair way to share the royalties in an agreement?
- for the main song
- for other variations including instrumental versions etc.
Thanks in advance all
