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.
Please make sure no one can 
know which one of us is playing,
‫رجاءً احرص على ألّا يعرف أحد من منا تعزف،
Die Leute sollen allein den Klang beurteilen.
Sie sollen nicht sehen können, wer spielt.
Haz que no sepan quién está tocando
Haz que no sepan quién está tocando
Pour que ce soit le plus juste possible,
j’aimerais une audition à l’aveugle.
Vorrei che nessuno veda chi si sta esibendo,
Para que possam julgar apenas o som,
Пусть нас выбирают только по игре.
