How to place a TextScript in the middle of the Staff?

[Michael Gerdau]

Hi list!

I'm trying to place an articulation right in the middle of the Staff and 
I seem to lack the proper incantation. When I increase Y-offset to e.g. 
#3 the little "z" is printed above the Staff. I want it to appear at 
about the gis position on top of the stem. What do I have to adjust to 
make it work?

\version "2.25.2"

music = \relative d' {
  \override TextScript.Y-offset=#2
  \override TextScript.X-offset=#0.5
  d2_\markup { \musicglyph "z" }\repeatTie r2
}

\score {
  \music
}

Kind regards,
Michael
