ly/chord-modifiers-init.ly:49: <c g>1-\markup { \super "5" }
This looks out of whack with the preceding definition of
\partialJazzMusic (which however has its own powerchord definition).
Maybe move the whole definition up to after \ignatzekExceptionMusic
where it logically belongs and which uses the same kind of superscript?

The way this is arranged currently, it reads jarringly.
