removed since the answer is basically a repetition with instances of
\remote peppered in.

Well, LilyPond has no way to guess how complex your variables are and
whether you are going to use them just once or multiple times and where
to look for errors.  So it assumes you are interested in the actual
source location.

Well, it's not very complicated and might help with debugging.  Try
this.  You might want to try thinking of a better name, though.

\version "2.19.65"

  cha -- ka -- ti -- ki

}

dak = \remote \lyricmode {

}

ch = \remote {a16 a a a}
da = \remote {\times 2/3 {a16 a a }}
