### 2.9.5 Typesetting Kievan square notation

#### Kievan contexts

As with Mensural and Gregorian notation, the predefined KievanVoice and KievanStaff contexts can be used to engrave a piece in square notation. These contexts initialize all relevant context properties and grob properties to proper values, so you can immediately go ahead entering the chant: 

\score {
<<
\new KievanVoice = "melody" \transpose c c' {
c4 c c c c2 b,\longa
\bar "kievan"
}
\new Lyrics \lyricsto "melody" {
Го -- спо -- ди по -- ми -- луй.
}
>>
}

LilyPond supports Kievan notation of the Synodal style, as used in the corpus of chantbooks printed by the Russian Holy Synod in the 1910's and recently reprinted by the Moscow Patriarchate Publishing House. LilyPond does not support the older (less common) forms of Kievan notation that were used in Galicia to notate Rusyn plainchant. 

#### Kievan clefs

There is only one clef used in Kievan notation (the Tse-fa-ut Clef). It is used to indicate the position of c: 

  \clef "kievan-do"
c

For Kievan square notation, the appropriate note head style needs to be chosen. This is accomplished by setting the style property of the NoteHead object to kievan. 

The Kievan final note, which usually comes at the end of a piece of music, may be selected by setting the duration to \longa. The Kievan recitative mark, used to indicate the chanting of several syllables on one note, may be selected by setting the duration to \breve. The following example demonstrates the various Kievan note heads: 

\autoBeamOff
b'1 b'2 b'4 b'8 b'\breve b'\longa

LilyPond automatically determines if the stem up or stem down form of a note is drawn. When setting chant in square notation, however, it is customary to have the stems point in the same direction within a single melisma. This can be done manually by setting the direction property of the Stem object. 

#### Kievan accidentals

The kievan style for accidentals is selected with the glyph-name-alist property of the grob Accidental. The kievan style provides a sharp and a flat sign different from the default style. There is no natural sign in Kievan notation. The sharp sign is not used in Synodal music but may occur in earlier manuscripts. It has been included primarily for the sake of compatibility. 

\clef "kievan-do"
\override Accidental #'glyph-name-alist =
#alteration-kievan-glyph-name-alist
bes' dis,

#### Kievan bar line

A decorative figure is commonly placed at the end of a piece of Kievan notation, which may be called the Kievan final bar line. It can be invoked as \bar "kievan". 

  \clef "kievan-do"
