When I put in:
\version "2.18.2"
\score {
\new PianoStaff <<
%Right Hand
\new Staff \relative c'' { \clef bass R1 R1 }
%Left hand
\new Staff \relative c, {\time 2/2 \clef bass \slashedGrace des8 c2}>>
}
for the right hand, there is a treble clef before the bass clef. I only want a bass clef at the beginning of the right hand. When I remove the "\slashedGrace des8", the treble clef goes away. How do I keep the slashed grace note but not have a treble clef in the right hand first?
