The Free Music Philosophy[1] generally encourages creators to free music using whatever language or methods they wish. A Free Music Public License (FMPL)[2] is available for those who prefer a formal approach.Some free music is licensed under licenses that are intended for software (like the GPL) or other writings (the GFDL). But there are also licenses especially for music and other works of art, such as Free To Use's Free To Use License, EFF's Open Audio License, LinuxTag's Open Music License, the Free Art license and some of the Creative Commons Licences.
