After looking into it some more I think it's unlikely that an exact translation into a different notation system qualifies as a derivative work. "The transformation, modification or adaption of the work must be substantial and bear its author's personality to be original and thus protected by copyright."[1]
If that's right, then I think something like the following should work for attribution statements: Translated into Clairnote music notation using LilyPond by Paul Morris. Original LilyPond file from the Mutopia Project, typeset in standard music notation by Nikos Kouremenos (© 2014, Mutopia-2014/03/24-519), used under a Creative Commons Attribution-ShareAlike 4.0 International license — http://creativecommons.org/licenses/ — free to distribute, modify, and perform.

Please let me know if I'm off track here, or if these need to be improved in some way.
