Creating slurs across voices
In some situations it is necessary to create slurs between notes from
different voices. The solution is to add invisible notes to one of the
voices, using \hideNotes.
This example is measure 235 of the Ciaconna from Bach’s second partita for solo violin, BWV 1004.
\relative c' { << { d16( a') s a s a[ s a] s a[ s a] } \\ { \slurUp bes,16[ s e]( \hideNotes a) \unHideNotes f[( \hideNotes a) \unHideNotes fis]( \hideNotes a) \unHideNotes g[( \hideNotes a) \unHideNotes gis]( \hideNotes a) } >> }
