Using <code>\override Slur.positions</code> it is possible to set the vertical position of the start and end points of a slur to absolute values (or rather, forcing LilyPond's slur algorithm to consider these values as desired). In many cases, this means a lot of trial and error until good values are found. You probably have tried the <code>\offset</code> command next just to find out that it doesn't work for slurs, emitting a warning instead.

The code in this snippet allows you to tweak the vertical start and end positions by specifying ''relative'' changes, similar to <code>\offset</code>.

Syntax: <code>\offsetPositions #'(</code><code>dy1</code><code> . </code><code>dy2</code><code>)</code>

<lilypond version="2.24.0">
offsetPositions =
#(define-music-function (offsets) (number-pair?)
#{
\once \override Slur.control-points =
#(lambda (grob)
(match-let ((((_ . y1) _ _ (_ . y2))
(ly:slur::calc-control-points grob))
((off1 . off2) offsets))
(set! (ly:grob-property grob 'positions)
(cons (+ y1 off1) (+ y2 off2)))
(ly:slur::calc-control-points grob)))
#})

\relative c'' {
c4(^"default" c, d2)
\offsetPositions #'(0 . 1)
c'4(^"(0 . 1)" c, d2)
\offsetPositions #'(0 . 2)
c'4(^"(0 . 2)" c, d2)
\bar "||"
g4(^"default" a d'2)
\offsetPositions #'(1 . 0)
g,,4(^"(1 . 0)" a d'2)
\offsetPositions #'(2 . 0)
g,,4(^"(2 . 0)" a d'2)
}
