Can we copyright a musical chord progression?
<p>Can we copyright a musical chord progression?</p>
<p>I've heard it said that musical chord progressions are not protected
if someone writes a new melody over the chords.</p>

<p>There are lots of ways that you could analyze the question, but one of the easiest is to consider that any remotely musical chord progression has already been invented and is now in the public domain.</p>
<p>You could copyright your particular performance of that chord progression, but the underlying composition that you are performing would be in the public domain already.</p>
