Re: trouble changing notehead size on percussion staff

[Niki Pantelias]

  Sorry -- forgot to paste in the .ly.  Here it is now.

\include "english.ly"

papersize = "letter"
\include "paper20.ly"

\include "drumpitch-init.ly"
\version "2.0.0"

Scale =
  \context Voice
  \notes
  {
    \time 4/4
    bd4 tomfl cymr tomfh
    \property Thread.NoteHead \override #'font-relative-size = #-3
    tomml4 cymr hho  tommh | 
    \property Thread.NoteHead \revert #'font-relative-size
    sn  hh cymr cymc |
    \bar"|."
  }

\include "english.ly"

\score {
  \apply #(drums->paper 'drums)
  \new Staff {
    \clef percussion
    \Scale
     }
 \paper { papersize = "letter"
          linewidth = \hsize - 0.9 \in }
 }
