Like this, perhaps? I can add it if this looks OK.
\version 2.15.36
\include english.ly
\relative c'' {
% normal tie
d4 ~
% Longer ties so you can see the shapes better
% Since the minimum-length is longer, the normal but wider tie
% is taller than the normal, short tie.
\override Tie #'minimum-length = #7
d ~
% Low ratio = flattened
\once \override Tie #'details #'ratio = #0.05
d ~
% High ratio = taller than normal
\once \override Tie #'details #'ratio = #1
d ~
% Reduce height = not as tall, but less flat than ratio = 0.05
\once \override Tie #'details #'height-limit = #0.5
d ~
% Large height-limit
% The tie still doesn't reach the full height limit
% because 'ratio' is at its default of 0.333 here.
\once \override Tie #'details #'height-limit = #3
d4 ~
% With both tweaks you get a big, loopy tie.
\once \override Tie #'details #'ratio = #1
\once \override Tie #'details #'height-limit = #3
d4 ~
d4
}

Understood. I realized later that what threw me about the Tie reference was the
formatting of 'details:
'((ratio . 0.333) (center-staff-line-clearance . 0.6) (tip-staff-line-clearance
. 0.45) (note-head-gap . 0.2) (stem-gap . 0.35) (height-limit . 1.0)
(horizontal-distance-penalty-factor . 10) (same-dir-as-stem-penalty . 8)
(min-length-penalty-factor . 26) (tie-tie-collision-distance . 0.45)
(tie-tie-collision-penalty . 25.0) (intra-space-threshold . 1.25)
(outer-tie-vertical-distance-symmetry-penalty-factor . 10)
(outer-tie-length-symmetry-penalty-factor . 10)
(vertical-distance-penalty-factor . 7) (outer-tie-vertical-gap . 0.25)
(multi-tie-region-size . 3) (single-tie-region-size . 4) (between-length-limit
. 1.0))
vs, maybe something like this:
'(
(ratio . 0.333)
(center-staff-line-clearance . 0.6)
(tip-staff-line-clearance . 0.45)
(note-head-gap . 0.2)
(stem-gap . 0.35)
(height-limit . 1.0)
(horizontal-distance-penalty-factor . 10)
(same-dir-as-stem-penalty . 8)
(min-length-penalty-factor . 26)
(tie-tie-collision-distance . 0.45)
(tie-tie-collision-penalty . 25.0)
(intra-space-threshold . 1.25)
(outer-tie-vertical-distance-symmetry-penalty-factor . 10)
(outer-tie-length-symmetry-penalty-factor . 10)
(vertical-distance-penalty-factor . 7)
(outer-tie-vertical-gap . 0.25)
(multi-tie-region-size . 3)
(single-tie-region-size . 4)
(between-length-limit . 1.0)
)
In the latter, it's very easy for the eye to scan the detail names.

Re: Flatten a tie without hardcoding control points?
Hi James,
On Fri, Apr 20, 2012 at 3:32 AM, James Harkins jamshar...@gmail.com wrote:
Maybe a simple question: Is there a way to flatten the curve of a tie that
is as easy as overriding ratio for slurs?
You can override 'ratio for ties too:
\override Tie #'details #'ratio = #0.2
Another possibility is to override 'height-limit:
\override Tie #'details #'height-limit = #0.75
I found control-points and this does change the tie's shape. But, I don't
need to modify the x-extent, only the y-extent. It looks to me as if
overriding the control points means that I would have to re-edit the
control points by hand if horizontal spacing changes (which could happen,
say, if I take the piece to the US and have to change the paper to letter
size instead of A4).
I found TieColumn's Y-extent property, but overriding it like this takes
no effect:
\once \override TieColumn #'Y-extent = #'(1 . 1.5)
Also doesn't change the result in any way if the pair of numbers is
reversed: (1.5 . 1).
Searched LSR for tie, didn't find anything quite like this. I'm fairly
sure a scheme function could handle it, but I'm probably a good year or two
away from being able to attempt something like that on my own.
As far as easier control of 'control-points goes, you can modify
http://lsr.dsi.unimi.it/LSR/Snippet?id=639 like so:
shapeTie =
#(define-music-function (parser location offsets) (list?)
#{
\once \override Tie #'control-points = #(alter-curve offsets)
#})
#(define ((alter-curve offsets) grob)
(let ((coords (ly:tie::calc-control-points grob)))
(define (add-offsets coords offsets)
(if (null? coords)
'()
(cons
(cons (+ (caar coords) (car offsets))
(+ (cdar coords) (cadr offsets)))
(add-offsets (cdr coords) (cddr offsets)
(add-offsets coords offsets)))
\relative c'' {
c~ c
\shapeTie #'(0 0 0 -0.15 0 -0.15 0 0)
c~ c
}
This way the shape of the tie is modified by offsetting lilypond's default
rather than you having to create the control points from scratch.
HTH,
David

Hi,
Oops--should have included the version. I'm using 2.15.37. With 2.14.2
and before you need the dollar sign:
shapeTie =
#(define-music-function (parser location offsets) (list?)
#{
\once \override Tie #'control-points = #(alter-curve $offsets)
#})
