How to get music rights
Figure out what rights you need.
There are two different licenses you need before you can use a piece of music: the synchronization license and the master use license. Each license confers different rights to the holder, but both are necessary to use a piece of music, for example, in a film.

Available options: (1). The master use license is required to have the full rights your instrument should already have. 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.; (2). 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.; (3). Decide which one will get you the exclusive rights to the music. 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.; (4). 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.;
The answer is:
(2).
