Something to understand about Copyright: the ONLY thing protected under copyright is the melody and the lyrics. Not the chords, not the chord progression, not the cool riff that you came up with, not the drum loop, etc...only the melody and the lyrics.
That said, if all you contribute to a song is the chords and someone wants to include your name on the copyright form as a song writer, good enough, but if they refuse because all you contributed were chords, it's within their right to do that because, again, chords do not constitute the "song" in the eyes of the Library of Congress.
Regardless of what you do/play/write/etc...try to get everything in writing before the session. Even if it's just a signed letter of intent or whatever, that's better than nothing at all.
...uhhh...I am not so sure about this!...to check I logged onto a legal forum and posed this question realy quite specifically!
here is the link:
http://forum.freeadvice.com/copyrights-trademarks-39/i-wrote-music-she-wrote-lyrics-melody-431338.html#post2048725here is the question and answer I got...I did this becauase as a lawyer in my past explained it to me a copyright is not to say that you own the the chord changes ...but to establish your ownership stake in a song...and your legal right to your portion of ownership will not be denied because your imput was not the melody or lyrics!...
here is the text from the legal forum..the questionI wrote the music and she wrote the lyrics and melody..
What is the name of your state (only U.S. law)? Texas and NY
I have seen multiple posts that don't quite get to this exact question and the answer has always been that everyone involved owns an equal part of the copyright as long as there is nothing against that premise in writing.
The reason I ask this over is because I have always been told that you can only copyright the lyrics and the melody!
Not the chords or the that funky music track that the song was written to...Just the melody and the lyrics...
What is the real deal?
example is...Sally says lets hit the studio to write!...I show up...I throw down this slammin track (drums, piano guitar etc) she starts putting this melody an lyrics to it...
I wrote the music that she wrote the lyrics and melody to...do we split the copyright?
Once again ...I was told only the lyrics and melody can be copyrighted...
thanx fo answering
here is the answer they gave...Your understanding is incorrect. The "song" is copyrighted -- the whole thing, not the individual parts. There is one copyright for the entire song, that's it. There may also be a separate copyright for the recording of the song, but there are not separate copyrights for individual pieces of a song, at least in a collaboration like you describe.
I have quite a few item in the library of congress registered this way....
