For something like this I put the phrases you want to use in two different
places in variables.

musicA = \relative{
       \tuplet 3/2 16 { c32 d e f e f g f e d c d  }
       \tuplet 3/2 4 { c8 d e f e f g f e
}

music = \relative{ c1 d \musicA d1 c }
        
practice = \relative{ \set Score.currentBarNumber = #3 \musicA }
