Taki decides that the band will choose the euphonium soli player by voting on one final audition. Kumiko then decides that they should choose based on sound alone, and so the two of them audition anonymously.
I'm putting everything I've done 
until now into this one moment.
‫سأضع كلّ ما فعلته حتى الآن في هذه اللحظة.
Ich muss ihnen alles zeigen,
was ich bisher …
Voy a poner toda la carne en el asador.
Voy a poner toda la carne en el asador.
Je vais leur montrer
tout le travail accompli…
Metterò in questa esibizione tutti gli sforzi
Estou colocando tudo o que fiz
até agora nesse único momento...
Покажу всё, чему училась…
ради этого момента.
