Wow!
What a difference right-align makes to the clarity and readability of this

Re: first trial with arranger.ly

[Gilles Thibault]

Unbound variable: expand-notes-and-chords-copy-of

I have changed something in file changePitch.ly.
The function expand-notes-and-chords-copy-of is defined in this new 
version

   https://github.com/gilles-th/arranger.ly/blob/master/changePitch.ly

Um, I have to make some progress to synchronize my personal versions and 
the final versions I put on GitHub.

Sorry for that.
