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: Starting lilypond 2.21.80 [Untitled (2)]...
