Re: Harp Pedal Spanners

[Alexandre Loomis]

Thanks, that was very helpful! Adding \tweak padding 1 to the original function and defining a continue function by

nextPed =
#(define-music-function (end-text) (markup?)
   #{
     \tweak bound-details.left.padding -3
     \startPed "" #end-text
   #})

makes many cases work or almost work by default. It still requires some tweaking, but far less.

It would be great to have more complete/robust harp pedal support in Lilypond!

Unfortunately, I believe TextSpanner still doesn’t implement shorten-pair… but you can always use padding to fake it:

startPed =
#(define-music-function (start-text end-text) (markup? markup?)
   #{
     \tweak dash-fraction #1.0
     \tweak bound-details.left.text #start-text
     \tweak bound-details.left.stencil-align-dir-y #CENTER
     \tweak font-shape #'upright
     \tweak bound-details.right.text #end-text
     \tweak bound-details.right.stencil-align-dir-y #CENTER
     \tweak bound-details.left-broken.text ##f
     \tweak bound-details.right-broken.text ##f
     \tweak bound-details.right.padding 4
     \tweak padding 1
     \startTextSpan
   #})

endPed = \stopTextSpan

RH = \relative es'' {
  ces'16  gis f  gis  des8 r a'16 ges es  ges d8 r |
}

Pedals = {
  s4_\startPed "G♯" " ♭" s s \endPed _\startPed "" "♮" s4 \endPed _"D♮" |
}

\score {
  \new Staff <<
    \new Voice \RH
    \new Voice \Pedals
  >>
}

Maybe Someone™ will have a more automatic and flexible method, but maybe this gives you a hint in the right direction?

Best,
Kieren.
