espacement entre staffs

[Daniel Cartron]

Bonjour,

Alors mon petit bout de code qui ne fait pas ce que je veux, à savoir que 
l'espacement entre la ligne de doigré et celle du dessous est énorme et j'ai 
beau essayer des override de verticalaxis ou autre rien à faire...

Merci d'avance.

  \new Staff \with {
  \override StringNumber #'stencil = #point-stencil
  \override Fingering #'stencil = #point-stencil
  \override TextScript #'stencil = ##f
  }
