Examples

• Sets the predefined Sims notation style for 72-EDO, selects the English note names, and draws the accidentals with the Bravura font.

  ekmFont = "Bravura"
  \include "ekmel.ily"
  \language "english"
  \ekmStyle sims

• Sets the predefined Stein/Zimmermann notation style (stz) for quarter-tones (24-EDO) and modifies it into a custom notation style with the Sagittal flat 11 medium diesis down symbol (U+E327) for three-quarter-tones flat, and two sharp symbols (U+E262) for double-sharp.

  \include "ekmel-24.ily"
  \ekmStyle stz
  \ekmUserStyle myNotation #'(
    (-3/4 #xE327)
    (1 #xE262 #xE262))

• This is the same example as above but it makes use of the corresponding Scheme symbols.

  \include "ekmel-24.ily"
  \ekmStyle stz
  \ekmUserStyle myNotation #`(
    (,THREE-Q-FLAT #xE327)
    (,DOUBLE-SHARP #xE262 #xE262))

• Sets the HEWM (Helmholtz/Ellis/Wolf/Monzo) notation for 72-EDO and selects the English note names. Note that double-flat is defined with #\b #\b which is drawn with a padding contrary to "bb".

  \include "ekmel.ily"
  \language "english"
  \ekmUserStyle hewm #'(
    (1 #\x)
    (-1 #\b #\b)
    (1/2 #\#)
    (-1/2 #\b)
    (1/4 #\^)
    (-1/4 #\v)
    (1/6 #\>)
    (-1/6 #\<)
    (1/12 #\+)
    (-1/12 #\-))

• Sets the notation after Karlheinz Stockhausen for 24-EDO with the fractional sharp symbols (U+ED58, U+ED5A), and the quarter-tone flat symbol (U+ED59).

  \include "ekmel-24.ily"
  \ekmStyle stz
  \ekmUserStyle stockhausen #'(
    (1/4 #xED58)
    (-1/4 #xED59)
    (3/4 #xED5A)
    (-3/4 #xED59 #xE260))

• Sets a variant of the Hesse notation style for 72-EDO using SMuFL characters: Gould arrows (U+E27A, U+E27B), Sims half arrows (U+E2A4, U+E2A1), and Bosanquet commatic symbols (U+E479, U+E47A). It is very similar to the Arrow notation style.

  \include "ekmel.ily"
  \ekmUserStyle smuflHesse #'(
    (1/4 #xE27A)
    (-1/4 #xE27B)
    (1/6 #xE2A4)
    (-1/6 #xE2A1)
    (1/12 #xE479)
    (-1/12 #xE47A))

• Sets the Standard sharp/flat symbols, single thru quintuple, like the predefined Diatonic notation style (dia) but for quarter-tones (24-EDO). The quadruple symbols (U+F61C, U+F61D) are private supplements of Ekmelos. Note that here, the order of alterations is significant since the standard accidentals in the default notation style (stc) are rearranged.

  \include "ekmel-24.ily"
  \ekmUserStyle diaQuarter #'(
    (1 #xF61C)
    (-1 #xF61D)
    (3/4 #xE265)
    (-3/4 #xE266)
    (1/2 #xE263)
    (-1/2 #xE264)
    (1/4 #xE262)
    (-1/4 #xE260)
    (5/4 #xF61C #xE262)
    (-5/4 #xF61D #xE260))

• Sets single glyphs from LilyPond's Emmentaler font for 48-EDO, as well as parentheses for cautionary accidentals. ±9/8 and ±5/4 are omitted here since they are set automatically to combinations of ±1 with ±1/8 and ±1/4.

  \include "ekmel-48.ily"
  \ekmUserStyle lilysingle #`(
    (0    ,(markup #:natural))
    (1/8  ,(markup #:musicglyph "accidentals.natural.arrowup"))
    (-1/8 ,(markup #:musicglyph "accidentals.natural.arrowdown"))
    (1/4  ,(markup #:semisharp))
    (-1/4 ,(markup #:semiflat))
    (3/8  ,(markup #:musicglyph "accidentals.sharp.arrowdown"))
    (-3/8 ,(markup #:musicglyph "accidentals.flat.arrowup"))
    (1/2  ,(markup #:sharp))
    (-1/2 ,(markup #:flat))
    (5/8  ,(markup #:musicglyph "accidentals.sharp.arrowup"))
    (-5/8 ,(markup #:musicglyph "accidentals.flat.arrowdown"))
    (3/4  ,(markup #:sesquisharp))
    (-3/4 ,(markup #:sesquiflat))
    (7/8  ,(markup #:musicglyph "accidentals.sharp.slashslashslash.stemstem"))
    (-7/8 ,(markup #:musicglyph "accidentals.flatflat.slash"))
    (1    ,(markup #:doublesharp))
    (-1   ,(markup #:doubleflat))
    (leftparen ,(markup #:musicglyph "accidentals.leftparen"))
    (rightparen ,(markup #:musicglyph "accidentals.rightparen")))

• Sets alteration values instead of accidental symbols with the default accidental in the void notation style. The values are drawn with the command \ekmelic-fraction and with a 3 steps smaller font size. It is similar to the alteration notation style.

  #(define-markup-command (numeric-accidental layout props)
    ()
    (let ((alt (ly:chain-assoc-get 'alteration props 0)))
      (interpret-markup layout
        (cons '((font-size . -3)) props)
        (markup #:vcenter #:ekmelic-fraction alt))))
  
  \ekmStyle void
  \ekmUserStyle numeric #`(
    (default ,(markup #:numeric-accidental)))
