Oh dear, but you are asking for it ! If one is adept with scheme, some or even much of the following can be automated. Even so, it's quite a trip down the rabbit hole and only you can decide if it is worth the grief. You can, of course, write your own code to shape and position ties and place it in your style file. The example code in the notation reference under "difficult tweaks" is the model to follow. This could include any number of conditions and calculations. However, although the left endpoint and the inner control points can be determined from the first note of the tie (X-offset = 0, Y-offset = position on the staff), I know of no way to access the second note's position directly. Fortunately, the X-offset of the right endpoint as determined by LilyPond (which varies in relation to the note) can be retrieved: \override Score.Tie #'after-line-breaking = #(lambda (grob) (let* ( (noteL (ly:grob-parent (ly:grob-original grob) X)) % left notehead (endX (car (cadddr (ly:tie::calc-control-points grob)))) % right endpoint of tie (dotX (ly:duration-dot-count (ly:event-property (event-cause noteL) 'duration))) % number of dots on left notehead (noteY (ly:grob-property noteL 'Y-offset)) % vertical position of notehead (taiDir (ly:tie::calc-direction grob)) % tie direction according to LilyPond % … … … many, many things would follow to account for most, % if not all, possibilities I know almost nothing of scheme and have gleaned these bits from the very nice and intelligent people on this forum. You'll need a good bit of scheme, a deep understanding of the Bezier function (in order to quantize the hump and avoid staff-line collisions), and a couple hours/days/months to experiment, if you plan to go this route. A similar routine could be created incorporating variables along with "\once \override…" for adjusting occasional, rather than default, behavior. % freak not, remember to breathe % You can also separate the chord into different voices and use: \override Staff.NoteColumn #'ignore-collision = ##t % and afterwards, ##f to allow the notes to line up vertically. (You would have to manually offset seconds.) Then, each voice can have its own command, allowing you to realize your dream of controlling the ties independently: \once \override Voice.Tie #'control-points = … You can, of course, create definitions and shortcuts to simplify the process. You may need more than four voices: voiceFive = #(context-spec-music (make-voice-props-set 4) 'Voice) … voiceNine = #(context-spec-music (make-voice-props-set 8) 'Voice) You will certainly need some patience, and you will probably only resort to these measures under compulsion. Print publishers usually do in fact compel copyists to make these emendations; I applaud your standards and desire for clarity. Oh, and one other trick, not as flexible as the snippet Eluze mentioned, but my battered mind finds this easier (does version 2.14 have the snippet built in?): If, in your style file, you set all ties to a low layer; for instance: \override Score.Tie #'layer = #-2 you can then put something like this in your definitions file: blnkIt = #(define-music-function (parser location left bottom width height) (number? number? number? number?) #{ \new Voice { \voiceNine \once \override Voice.TextScript #'layer = #-1 \once \override Voice.TextScript #'outside-staff-priority = ##f \once \override Voice.TextScript #'X-extent = #'(0 . 0) \once \override Voice.TextScript #'Y-extent = #'(0 . 0) \once \override Voice.TextScript #'X-offset = #0 \once \override Voice.TextScript #'Y-offset = #0 s1*0-\markup { \with-color #white \filled-box #(cons $left (+ $left $width)) #(cons $bottom (+ $bottom $height)) #0 } } #} ) Size and position the box to blank out any portion of the tie (or anything you might assign to the lower layer). $left = 0 is the point in the music where you place the command; $bottom = 0 is the center line of the staff. I use voiceNine so it can be positioned independently of any other text at that point in the music. If you can't see where the box is, change #white to #red until you get it in place. To blank out around a downward stem, you might try: \blnkIt #-0.25 #-2 #0.6 #4 e'4 and adjust the #-2 and #4 for the vertical position and height. Feel better now? Red pill or blue pill? (Did anyone ever try both?)
