If you use samples of music by other authors in your work, ensure that you get permission to use the work before you attempt to publish or sell your work. Similarly, if you use loops or samples available via sample collections etc. ensure that these are licensed as free to use, or obtain permission first.
If you need to get permission to use a piece of music, normally the best place to start is with the last know publisher for the work. They will certainly know how to get permission to use the work.
Where music is written as a group effort, we recommend that you draw up an agreement to clarify issues, such as which rights belong to which member, and how royalties would be distributed in the event that members of your group leave.
For successful commercial bands, incorporation is also an option. As with a normal incorporated company, the band members would own shares in the band/company. In this situation, a band member would typically sell his shares to the other members if he decided to leave.
Copyright does not apply to names, neither will it apply to single phrases or slogans. Names may however be regionally protected as a trademark which may be carried out via national patent and trademark offices. To qualify the name should be distinctive, not deceptive or contrary to law or morality, and not similar to previously registered band names.
