Music
Copyright applies to a musical composition when it is set down in permanent form, either by writing it down or in any other manner. With a song there will usually be more than one copyright associated with it. If you are the composer of the music you will be the author of the musical work and will have copyright in that music. The lyrics of a song are protected separately by copyright as a literary work. The person who writes the lyrics will own the copyright in the words.
If your work is subsequently recorded the sound recording will also have copyright protection. The producer of the recording will own the copyright in the sound recording.
Composers of music may also have moral rights in their work.
Copyright is like any form of physical property in that you can buy it, sell it, inherit or otherwise transfer it, wholly or in part. Therefore, some or all of the economic rights may subsequently belong to someone other than you, the first owner.
