\voiceTwo _is_ music rather than a music command.

\void \displayLilyMusic \voiceTwo delivers

{
  \override Voice.AccidentalSuggestion.direction = #-1
  \override Voice.DotColumn.direction = #-1
  \override Voice.Dots.direction = #-1
  \override Voice.Fingering.direction = #-1

}

Which is a whole lot of music.

If you want to tag a music command (namely something that still needs
arguments before being complete music), there is \etc to do the job: you
can write something like

    baba = \tag music \tweak color #red \etc

and then

    \baba c'4

expands to

    \tag music \tweak color #red c'4
