Re: Change staff and cross staff

Oh, this is so close! The snippet provided doesn't have the slur from
the lower g sharp to the b in it, so I tried adding it. The b is in
the lower hand so I tried slurring to the e and then use \shape to fix
it, but it produces a programming error. Here's the modified
snippet...

%%% Start
\version "2.21.7"

\layout { \context { \PianoStaff \consists #Span_stem_engraver } }

rhmusic = {
\time 3/4 \key e \major
\change Staff = "lower"
\stemUp <gis b>8[( r16 % added start paren
\change Staff = "upper" e'16]) % added end paren
}

lhmusic = {
\key e \major
\clef "bass"
<< { s8. \crossStaff {b16} } \\ { e,4 } >>
}

\new PianoStaff
<<
\new Staff = "upper" {\rhmusic}
\new Staff = "lower"{\lhmusic}

%%% End

...and here's the output I get:
