Attribution statements for Mutopia Project works

[Paul Morris]

Greetings all,

Are there established practices or examples of how to properly attribute works 
from the Mutopia Project that are licensed with a Creative Commons license?  
Say if you make a derivative work based on one?  

I have made (what I understand to be) derivative works by translating or 
transcribing some pieces into an alternative music notation system (Clairnote, 
http://clairnote.org).  I came up with the following statement, based on the 
best practices described here:  
http://wiki.creativecommons.org/Best_practices_for_attribution  


Typeset using LilyPond in Clairnote music notation by Paul Morris. This work (© 
2014) is a derivative of the Mutopia Project work of the same title, typeset 
using LilyPond in standard music notation by Nikos Kouremenos (© 2014, 
Mutopia-2014/03/24-519). Both works are licensed under a Creative Commons 
Attribution-ShareAlike 4.0 International License — free to distribute, modify, 
and perform.


This statement fits on three lines and would appear in the footer on the first 
page (just like the current copyright/license statement for Mutopia files).  

Thanks for any feedback on this, especially from anyone who has experience with 
this.  It would be good to know that these statements are sufficient or if they 
could be improved.  You can see actual examples here: 
http://clairnote.org/sheet-music/  (see any pdf from that page except Twinkle 
Twinkle, Swinging on a Gate, or 180 Fiddle Tunes)

Thanks,
-Paul


P.S. For works in the public domain I would use slightly different wording:

Typeset using LilyPond in Clairnote music notation by Paul Morris. This work (© 
2014) is a derivative of the Mutopia Project work of the same title, typeset 
using LilyPond in standard music notation and placed in the public domain by
