I'm trying to create a function to display harmonics as shown in the attached images.
harmonic1.png is in the alto clef with the sounded pitches written in the
treble clef
[image: Inline images 3]
harmonic4.png is an acciaccatura all in the alto clef
[image: Inline images 4]
This is where I got to:
harmonicFingered =
#(define-music-function
(parser location note) (ly:music?)
#{
\stemNeutral #note
#})
harmonicActual =
#(define-music-function
(parser location note) (ly:music?)
#{
\once \override Accidental #'font-size = #-4
\once \override Accidental #'extra-offset = #'(2 . 0)
\tweak Stem #'stencil ##f
\tweak Flag #'stencil ##f
\tweak #'font-size #-4
\tweak #'X-offset #1.75
#note
#})
harmonicActualGrace =
#(define-music-function
(parser location note) (ly:music?)
#{
\once \override Accidental #'font-size = #-4
\tweak Stem #'stencil ##f
\tweak Flag #'stencil ##f
\tweak #'font-size #-4
#note
#})
harmonicBoth =
#(define-music-function (parser location fingered actual) (ly:music?
ly:music?)
#{
<<{\harmonicFingered $fingered } \new Voice {\harmonicActual $actual }>>
\oneVoice
#})
harmonicGrace =
#(define-music-function (parser location fingered actual) (ly:music?
ly:music?)
#{
<<{\harmonicFingered $fingered } \new Voice {\harmonicActualGrace $actual
}>> \oneVoice
#})
(for everything except acciaccaturas/grace notes I am putting the sounded
pitch after the fingered pitch to be consistent (the original score has
some before and some after) - for acciaccaturas I am aligning them
vertically).
Which gets things more or less right for most situations -
e.g. \harmonicBoth <e\harmonic>4_\flageolet e'}
However, I would be very grateful if someone could help me to
a) clean up the function a bit to be more Lilypondian - I don't think I
have done things in the correct/logical way here (I am quite new to this!)
b) if possible allow adding a treble clef or ottava to the sounded pitch
c) make slurs/tuplet brackets etc. avoid the notehead in the same way as
they do normal noteheads.
As an aside, why do \flageolets always appear above the note unless
specified with a _?
Many thanks!
