Separating key cancellations from key signature changes ¶

By default, the accidentals used for key cancellations are placed adjacent to those for key signature changes. This behavior can be changed by overriding the break-align-orders property of the BreakAlignment grob.

If you look up the definition of the break-alignment-interface in LilyPond’s Internals Reference, you get the following list of available break-align symbols:

ambitus
breathing-sign
clef
cue-clef
cue-end-clef
custos
key-cancellation
key-signature
left-edge
signum-repetitionis
staff-bar
staff-ellipsis
time-signature

From this list, we find that we want to move key-cancellation so that it comes before staff-bar. This is accomplished with the \breakAlignInsert function.

music = { \key es \major d'1 \bar "||"
          \key a \major d'1 }

{ <>^\markup "default"
  \music }

{ <>^\markup "cancellation first"
  \breakAlignInsert key-cancellation before staff-bar
  \music }
