This contract is for use with composers who are writing the musical score for a production. It should be used regardless of whether or not the composer is being paid for their services.
It is advisable to make the delivery date of the score (in Section 1 of the contract) as early as is feasible, in order to provide some padding. It is not uncommon for composers on student films to miss their deadline, so it’s better to assume that that might happen than to hope for the best. Most ideal would be setting delivery of the score for a date during the sound editing phase, so that you have a better sense of how everything’s coming together. If that’s not viable, set delivery for as many days before the mix date as your composer’s schedule will allow.
