I use the following:
----------------------------------------
#(use-modules (ice-9 optargs))
#(define*-public (mus:make-context context element #:key id (operations '()))
"Base function for building ContextSpeccedMusic objects."
(apply make-music (append (list 'ContextSpeccedMusic
'property-operations operations
'context-type context
'element element)
(if id (list 'context-id id) '()))))
#(define*-public (mus:override context layout property val #:optional once)
"Layout property override.
\once \override Voice.Fingering #'padding = #3
<=>
(mus:override 'Voice 'Fingering 'padding 3 #t)"
(mus:make-context context (make-music 'OverrideProperty
'once once
'grob-property property
'grob-value val
'symbol layout)))
#(define* (textshift dx dy #:optional once)
(ly:export
(mus:override 'Bottom 'TextScript 'extra-offset (cons dx dy) once)))
\score {
\notes {
\fatText
c'^"normal text"
#(textshift 3 2 #t)
c'^"shifted text once"
c'^"normal text"
}
}
