Mayu taking the soli part has made the concert band uneasy. Despite Kumiko's insistence that this is how it should be, several members take issue with Taki's decision.
So he could only have switch soloists 
because his criteria have changed.
‫لذا لا يمكنه تغيير عازفي السولو
‫إلّا إن كان معياره قد تغير.
Dass er diesmal getauscht hat, heißt doch,
dass sich seine Maßstäbe geändert haben.
Podría haber cambiado de solistas
solo porque cambiara su criterio.
Podría haber cambiado de solistas
solo porque cambiase su criterio.
Mais s’il a revu les effectifs,
c’est que ses critères ont changé, non ?
Eppure ha deciso di sostituiti con lei, 
come se avesse cambiato i criteri di scelta.
Então ele só poderia ter trocado 
o solo porque seu critério mudou.
Но он всё равно решил сменить солиста.
