Re: Help a newb: Formatting custom instrument names

[Leo Correia de Verdier]

I’m not sure if this is an interesting suggestion, but if you want this as the 
actual clef you could write 
%%%%%%%%%%%%%%
\once \override Staff.Clef.stencil = #ly:text-interface::print
  \once \override Staff.Clef.text = \markup {
    \override #'(font-size . -6.5)
    \unit-height-column { First second third fourth fifth sixth seventh eighth 
ninth tenth eleventh } }
  \once \override Staff.Clef.Y-offset = #5
  \clef treble % or whatever
%%%%%%%%%%%%%%
