LilyPond — Changes

This document lists changes and new features in LilyPond version 2.27.1 since 2.26.

Note: LilyPond releases can contain syntax changes, which may require modifications in your existing files written for older versions so that they work in the new version. To upgrade files, it is strongly recommended to use the convert-ly tool distributed with LilyPond, which is described in Updating files with convert-ly. convert-ly can perform almost all syntax updates automatically. Frescobaldi users can run convert-ly directly from Frescobaldi using “Tools > Update with convert-ly…”. Other editing environments with LilyPond support may provide a way to run convert-ly graphically.


New for musical notation


Rhythm improvements

  • By default, strictly alternating meters consisting of 4/4 and 2/2 are printed in a historic style using multiple C or cut-C symbols.
    {
      \time #'((2 . 2) (2 . 2))
      b'1 2 2
    }

  • The automatic beaming algorithm now can be told to interrupt an automatically created beam at some point using \beamBreak. Similarly, using \noBeamBreak, two adjoining notes can be forced to get beamed together:
    \relative {
      c''8 c c c d d \beamBreak d d
      \time 2/4
      c8 8 8 8
      8 8 \noBeamBreak 8 8
      4. 8 \noBeamBreak
      8 4 8
    }

Editorial annotation improvements

  • The Scheme function parenthesize-stencil got an optional argument to lengthen the parentheses.
  • The Scheme function bracketify-stencil got an optional argument to lengthen the brackets.

Text and font improvements

  • An equal sign was added to the Emmentaler font.
  • A senza-misura time signature was added to the Emmentaler font.

  • Text variant glyphs for common time and cut time symbols were added to the Emmentaler font. They can be either accessed directly as Unicode characters or using the \text-common-time and \text-cut-time markup commands.

  • Fonts may be changed in a single markup using \font-select. The font names for the serif, sans and typewriter families are chosen independently.
    \markup \font-select #'((sans . "DejaVu Sans")
                            (typewriter . "DejaVu Sans Mono"))
    {
      \sans \line { Sans-serif font. }
      \typewriter \line { Typewriter font. }
      \line { Default serif font. }
      \font-select #'(serif . "DejaVu Serif")
      \line { Changed serif font. }
    }

New for specialist notation

  • The chord name input x:1/x gets now rendered as ‘N.C./x’.
    \chords { d:1/d }

  • White mensural ligatures now support final ascending longae facing backwards, obey tweaks in more cases, and handle errors more gracefully.
    \score {
      \new PetrucciStaff {
        \clef "petrucci-c4"
        \[ g\breve f \tweak ligature-pes ##t c'\longa \]
      }
    }

  • Stanza numbers in lyrics are now created with a dedicated \stanza ... command. This replaces the former syntax \set stanza = ....
    \relative {
      c'4 c g' g
      a a g2
    }
    \addlyrics {
      \stanza "1."
      Twin -- kle, twin -- kle, lit -- tle star
    }
    \addlyrics {
      \stanza "2."
      When the bla -- zing sun is gone
    }

  • Stanza numbers in lyrics can now be auto-repeated at the beginning of each line. To activate this feature, set the stanzaReminders property to #t:
    \new Voice \relative {
      \key e \minor
      b'4 b a g
      fis2 e \break
      b'4 cis d b
      e2 dis \break
      e4 g fis fis
      e1
    }
    \addlyrics {
      \stanza "1."
      \set stanzaReminders = ##t
      Je -- su, mei -- ne Freu -- de,
      mei -- nes Her -- zens Wei -- de,
      \set stanzaReminderText = "(1st)"
      Je -- su, mei -- ne Zier.
    }
    \addlyrics {
      \stanza "2."
      Un -- ter dei -- nem Schir -- men
      bin ich vor den Stür -- men
      \set stanzaReminders = ##t
      \set stanzaReminderText = #make-tiny-markup
      al -- ler Fein -- de frei.
    }

  • An alternative to using \pes and \flexa (which internally do the same) is the command \~. This isn’t new (being introduced in 2003); however, it stayed undocumented and was broken for some time.
    \new VaticanaScore {
      \new VaticanaVoice \relative {
        \[ a \pes b \flexa g \]
      }
    }
    
    [image of music]
    \new VaticanaScore {
      \new VaticanaVoice \relative {
        \[ a \~ b \~ g \]
      }
    }

Miscellaneous improvements

  • The new commands \startGradualTempoChange and \stopGradualTempoChange describe a temporary departure from the prevailing tempo. Currently, these affect only MIDI output.
  • These functions, which have been deprecated since version 2.13.19, have been removed: \deprecatedcresc, \deprecatedendcresc, \deprecateddim, and \deprecatedenddim.
  • The glyph-name property of a NoteHead grob now contains a fully qualified glyph name, as documented. It is no longer necessary to replace the stencil just to draw a different note head glyph; setting this property suffices.
    {
      c'4
      \once\override NoteHead.glyph-name = "noteheads.s2triangle"
      c'4
    }

    As a side effect, the Scheme function note-head::calc-glyph-name is not needed anymore and will be removed after a deprecation cycle. Depending on the intended use case, its use may be replaced either by accessing the glyph-name property of a specific NoteHead grob, or by calling select-head-glyph for a specific notehead style and duration-log.
