That is an original bio!

Yup, there are a bunch of lyric-related grobs cooperating
to put spacing constraints so that the lyrics don't overlap,
hyphens are not too short, etc. Try switching off these
settings, like so:


\version "2.21"

bio_rhythm = {
      r8 c8-> 16-> 16 16 16 16-> 16 16 16-> 16 16-> 16 16->
      r16 c16 16-> 16 16-> 16 16 16 16-> 16 16 16 8-> 16 16->
      r8 \tuplet 3/2 { c16-> 16 16 } c16-> 16 16 16 \tuplet 3/2 { 8-> 8 
8 } c8-> r
      c16-> 16 16 16 16 16 16 16 16-> 16 16 16-> ~ 16 16 8
      r16 c16 16-> 16 16-> 16 16 16-> ~ 16 16 16 16-> ~ \tuplet 3/2 { 8 
8 r }
      c16-> 16 16 16-> ~ 16 16 16 16 c16-> 16 16 16 8-> 8
      r8 c16-> 16 16-> 16 16 16 16-> 16 16 16-> 16 16 8->
      r16 c16-> 16 16 16-> 16 16 16 16 16 8-> 8-- 8-> 8--
}
bio_rap = \lyricmode {

  }
}

\score {

    \new RhythmicStaff \bio_rhythm
    \addlyrics \bio_rap

}



At the same time, you'll realize why LilyPond was
refusing to space your music strictly proportionally
and be able to adjust line width and font size
settings accordingly.
