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.
That's why I'm here to play 
with all I've got today.
‫لذلك السبب أنا هنا للعزف بكل ما لدي اليوم.
Und darum werde ich heute
alles geben, was in mir steckt.
C’est pour ça qu’aujourd’hui,
je veux tout donner.
Pertanto, oggi ho intenzione
di esibirmi al meglio delle mie capacità.
É por isso que estou aqui,
para tocar com tudo o que tenho.
Поэтому сегодня
выложусь на все сто.
