I'm developing a sideline to my 'core' business of pre-school music classes, which will be to provide other organisations with backing tracks for them to use in their own classes, or for them to record their own vocals over the top.
Hw do I go about copyrighting and protecting my interests in the backing tracks? If they record their vocals over the top and produce a CD then I assume they hold the copyright in that particular production, however I still want to retain the rights to the underlying backing track. Can anyone tell me the best way of going about doing this?
