+
+Notes within a Kievan melisma are usually placed close to each other
+and the melismata separated by whitespace. This is done to allow
+the chanter to quickly identify the melodic structures of Znamenny
+chant. In LilyPond, melismata are treated as ligatures and the
+spacing is implemented by the @code{Kievan_ligature_engraver}.
+
+When the @code{KievanVoice} and @code{KievanStaff} contexts are used,
+the @code{Kievan_ligature_engraver} is enabled by default. In other
+contexts, it can be invoked by replacing the
@code{Ligature_bracket_engraver}
+with the @code{Kievan_ligature_engraver} in the layout block:
+
+@example
+\layout @{
+ \context @{
+ \Voice
+ \remove "Ligature_bracket_engraver"
+ \consists "Kievan_ligature_engraver"
+ @}
+@}
+@end example
+
+The spacing between the notes within a Kievan ligature can be controlled
+by setting the @code{padding} property of the @code{KievanLigature}.
+
+The following example demonstrates the use of Kievan ligatures:
+
+@lilypond[quote,ragged-right,verbatim]
+\score {
+ <<
+ \new KievanVoice = "melody" \transpose c c' {
+ \cadenzaOn
+ e2 \[ e4( d4 ) \] \[ c4( d e d ) \] e1 \bar "k"
