Re: Semi-flat insert to one instrument only

[Riad Abdel-Gawad]

Dear Jean,

Here is an example of the type of flat with slash I need.

The problem is that the "backward" flat is a Turkish (remnants from the Ottoman time Empire) notation and today Arab musicians prefer the "standard" notation, which is the "forward" flat with a slash through it (see attached pdf and code here pasted for that pic).

\version "2.22.1"
\include "hel-arabic.ly"


{
\new Staff \relative  
  \clef treble
\omit score.TimeSignature
\relative
\key c \rast
\cadenzaOn
c'1 c'1 edb'1 edb'1 c'1 eb'1 c'1 e'1 c'1 edb'\breve

}

If I have understood your request correctly, you could go for the
not-so-clean but functional:


\version "2.22.1"
\language "english"
\header {
   title = "Quintet"
   subtitle = "for Sout"
   subsubtitle = "for Samir Bendimered and Jan Rzewski"
   instrument = "soprano saxophone, percussion, piano, violin, contrabass"
   composer = "Riad Abdel-Gawad"
   copyright = "2022"
}

\layout {
   \context {
     \Score
     \override Accidental.stencil =
     #(lambda (grob)
        (let ((alteration (ly:grob-property grob 'alteration)))
          (if (eqv? alteration -1/4)
              (begin
                (ly:grob-set-property! grob 'restore-first #f)
                (ly:stencil-add
                 (ly:accidental-interface::print grob)
                 (ly:line-interface::line grob -0.18 0.7 1.3 1.65)))
              (ly:accidental-interface::print grob))))
   }
}


global = {
   \key g \minor
   \time 8/4
   \tempo 4=100
}

sopranoSax = \relative c'' {
   \global
   % Music follows here.
    }

drum = \drummode {
   \global
   % Drums follow here.

}

right = \relative c' {
   \global
   % Music follows here.

    }

left = \relative c' {
   \global

contrabass = \relative c {

   % Music follows here.
  }

sopranoSaxPart = \new Staff \with {
   instrumentName = "Soprano Sax"
   shortInstrumentName = "S. Sax"
   midiInstrument = "soprano sax"

drumsPart = \new DrumStaff \with {
   \consists "Instrument_name_engraver"

   \new Staff = "left" \with {
     midiInstrument = "acoustic grand"
   } { \clef bass \left }
 >>

violinPart = \new Staff \with {
   instrumentName = "Violin"
   shortInstrumentName = "Vln."
   midiInstrument = "violin"
} \violin

contrabassPart = \new Staff \with {
   instrumentName = "Contrabass"
   shortInstrumentName = "Contrabass"
   midiInstrument = "contrabass"
} { \clef bass \contrabass }

\score {
   <<
     \sopranoSaxPart
     \drumsPart
     \pianoPart
     \violinPart

   \layout { }
   \midi { }
}
