Printing tuplet brackets on the note head side

Whichever option you choose for controlling the tuplet bracket visibility, it will show or hide the tuplet bracket irrespectively of tuplet bracket placement (stem side or note head side). However, when placing the tuplet bracket on the note head side some authors recommend always printing the tuplet bracket. The option visible-over-note-heads can be used to achieve this.

music = \relative c'' {

  \tupletUp \tuplet 3/2 { c8 d e }
}

\new Voice {
  \relative c' {
    \override TextScript.staff-padding = #2.5

    \time 2/4
    \override TupletBracket.visible-over-note-heads = ##t
    \override Score.TextMark.non-musical = ##f
    <>^\markup "default" \music
    \override TupletBracket.bracket-visibility = #'if-no-beam
    <>^\markup \typewriter "if-no-beam" \music
