+Les objets @code{VerticalAlignment} et @code{VerticalAxisGroup}
+travaillent de concert. Comme leurs noms anglais l'indiquent,
+@code{VerticalAxisGroup} regroupe différents objets tels que les portées
+(@code{Staff}), les paroles (@code{Lyrics}) et ainsi de suite ; puis
+@code{VerticalAlignment} synchronise verticalement ces différents groupes.
+En général, il n'y a qu'un seul @code{VerticalAlignment} pour l'ensemble
+de la partition, mais chaque contexte @code{Staff}, @code{Lyrics}, etc.
+possède son propre @code{VerticalAxisGroup}.
