Hi, I make music with a partner, and want to specify the ownership of each song individually because I put significantly more time and knowledge into the music than he does. I have good knowledge of copyrights and the differences between the right in the composition and the right in the recorded composition but still some open questions: I thought about writing something like this per song (in addition to a partnership agreement):Individual Music Ownership AgreementSong name: "Supersong"1. Musical composition:Partner A: 80%Partner B: 20%2. Lyrics:Partner A: 50%Partner B: 50%3. Performance on recorded composition with the name "Supersong":Partner A: 100%Partner B: 0%4. Ownership of master:Partner A: 80%Partner B: 20%I am not sure whether 3 and 4 are handled separately or as one point. I know that usually whoever pays for the recording owns the master (traditionally the label but I record and mix in my studio). I have also heard that ownership of the master is equally shared in all participants including a label for example. Or can it be specified in detail as I have done above. Or does it make sense to value the recording and mixing as a "performance". Thanks a lot for any help.Pete
