I'm trying to transcribe Ravel's Alborada del Gracioso but when there are clef changes there tends to be a collision between the clef and the notes. How would I add space? And perhaps I'm writing it incorrectly, since I have one staff doing all the work. I don't know how to have cross staff beaming but with the notes written in different staffs.
\version "2.18.2"
up = {\change Staff = "up" }
down = { \change Staff = "down" }
\new PianoStaff <<
\new Staff = "up" { \clef bass \time 6/8 s4. \clef treble s4. }
\new Staff = "down" { \clef bass<d, a,>8 \up <d a> \down <d a> \clef treble \up <d' a'> \down <d' a'> \up <a' d'' a''> }
