[substeps] The master use license permits a piece of music as well as the master use license to train all your fellow artists who plan to play the instrument. Ending2: [substeps] The synchronization license grants the right to pair a piece of music with your visual image. The master use license grants the right to reproduce a specific recording of the piece in your work. Ending3: Decide which one will get you the exclusive rights to the music. [substeps] A master use license allows the holder to access the entire art of music without being charged a full fee for having been the owner of the original piece before it was stolen. Ending4: [substeps] When you are trying to get music rights, it's important to establish that both are rights. That way, if one is illegal, you can have the rights to both.
