Re: Clef change at the beginning of a staff

[Noeck]

That's also good. I thought the grace note causes problems if it is
different in different staves but this also works:

\version "2.18.2"

<<
\relative c'' { c c c c c1 }
\new Staff \relative c' {
  %%  Start with a bass clef :
  \clef bass
  %%  Use a hidden grace note (avoid any wrong calculation):
  \once\hideNotes\grace c64
  %%  Adjust the clef spacing:
  \once\override Staff.Clef.X-extent = #'(1 . 2)
  %%  Put in the treble clef:
  \clef treble
  c4 c c c | c1
}
>>
