Re: Stem extension question

[Rip _Mus]

Thank you for your valuable suggestions!

I took the music function by Pierre-Luc and modified as follows:

artificialHarmonicMod = #(define-music-function

                          (stopped touched result duration)

                          (ly:music? ly:music? ly:pitch? ly:duration?)

                          #{

                            <<

                              {

                                \voiceOne \stemDown

                                <$stopped $touched \harmonic>$duration

                              }

                              \new Voice

                              { \voiceTwo \once \omit Stem \once \omit Flag \parenthesize $result 32 ^\flageolet }

                            >> \oneVoice \stemNeutral

                          #})

\new Staff {

  \relative c' {

    \artificialHarmonicMod cis_~ fis cis'' 4

    \artificialHarmonicMod cis,, gis' gis'' 4

  }

}

In this way it is possible to put ties between common notes, for example.

Is there a way to insert an optional argument in the music function? I would have the possibility to express a post-event, like tremolo or glissando.

Thank you

I used this extensively (in Stravinsky and whatnot).

artificialHarmonic = #(define-music-function
                       (stopped touched result duration)
                       (ly:pitch? ly:pitch? ly:pitch? ly:duration?)
                       #{
                         \afterGrace
                         <$stopped
                         $touched \harmonic>$duration
                         \tweak NoteHead.font-size -6
                         \tweak Stem.stencil f
                         \tweak Beam.stencil f
                         \tweak Flag.stencil f
                         \parenthesize
                         $result \harmonic
                       #})

used as :
\artificialHarmonic ds,, fs as''1.

It works for me but is not quite perfect. For one, I would love for it
to generate only the midi for the $resulting note and not the whole
chord (which is musically totally irrelevant).

Hope it helps
