One of Sound! Euphonium‘s more remarkable traits is that, within its captivating world, not everyone is equally talented. Where other series use those left behind – by their lack of skill, practice, or motivation – for dramatic effect, rarely returning to them once they’ve served their purpose on the main character’s decisions, Sound! Euphonium celebrates them.
In showing and developing various narratives, Sound! Euphonium invites character comparison. The most obvious example is of Reina Kousaka and Kumiko Oumae. Both struggle with verbal communication – Reina preferring to express herself through music and Kumiko seemingly possessing large amounts of anxiety – which is what makes their developing friendship work. As evidenced in the series’ fifth episode, Reina begins to open up to Kumiko, and while Kumiko still stumbles over her own words, she has managed to overcome her fear of starting a conversation.
While Kumiko is the primary character, Sound! Euphonium relies on dialogue with others, along with her actions, to speak for her. In spite of the audience’s access to her thoughts, Kumiko is one who has trouble identifying what she truly wants, and her inner monologues reflect this, rarely offering her actual emotions.
When Reina Kousaka needs to express her emotions, she plays her trumpet. When that doesn’t work, she screams.
