Correction: Since we're in a throwaway voice anyway, we don't need all
those \once commands:
\version "2.23.4"
\relative c' {
\time 2/4
\key aes \major
ees'4
\after 8 \new Voice {
\set suggestAccidentals = ##t
\override AccidentalSuggestion.avoid-slur = #'inside
\override AccidentalSuggestion.font-size = -3
\override AccidentalSuggestion.script-priority = -1
\hideNotes
b16\turn
}
f8.[( aes32 c)]
}
The avoid-slur property seems not to be needed here, as the slur and the
turn are on opposing sides.
