Gauche is a professional cellist who plays for a small-town orchestra called the Venus Orchestra, as well as for the local cinema, in what appears to be the early twentieth century. He lives alone in a modest mill house on the outskirts of town, a setting that reflects his somewhat isolated and work-focused life. His role in the story is that of a struggling artist; while he is diligent and hardworking, his musical abilities are mediocre, and he is often the weakest member of his ensemble. During rehearsals for an upcoming performance of Beethoven’s Sixth Symphony, he is frequently berated by the conductor for his poor timing and lack of emotional feel for the music.

In terms of personality, Gauche is initially presented as irritable, impatient, and lacking in self-confidence. He is easily frustrated by his own perceived failures and reacts with hostility toward interruptions. When a cat visits him on the first night and asks him to play a piece by Schumann, Gauche is annoyed and instead plays a loud, violent piece called Tiger Hunt in India specifically to startle and frighten the animal away. Similarly, when a cuckoo bird asks for help practicing scales, Gauche feels that the bird sings better than he plays and chases it out, causing it to injure itself on a window. These early interactions reveal a character who is defensive, insecure, and prone to taking out his professional frustrations on others.

Despite this abrasive exterior, Gauche is not malicious. His motivations are rooted in a genuine desire to improve as a musician and to succeed in the upcoming concert, which is why the conductor’s criticism stings so deeply. Over the course of four nights, his motivations evolve from a simple need for technical correction to a deeper understanding of musical expression and empathy. The animals that visit him each night—a cat, a cuckoo, a tanuki (raccoon dog), and a mother mouse with her sick baby—serve as unconventional teachers. The tanuki helps him recognize issues with his rhythm, pointing out that he plays too slowly when trying to play quickly. The most significant relationship is with the mice. When a mother mouse asks him to heal her sick child with his music, explaining that the sound of his cello has already healed many other animals, Gauche softens. He places the tiny mouse inside the hole of his cello and plays a gentle rhapsody, successfully curing the creature. This act represents his turning point, where his playing becomes selfless and tender rather than technically driven or aggressive.

The character’s development is directly tied to these interactions. He moves from impatience and cruelty to a state of quiet realization and gratitude. After a successful concert, where his playing has clearly improved, he returns home and feels genuine remorse for how he treated the cuckoo, opening the window where the bird had hit its head. The story ends with Gauche at peace, having learned that technical skill must be balanced with feeling and that inspiration can come from unexpected places. His notable abilities are strictly musical; as a cellist, his primary skills include reading music and performing with an orchestra. However, his most significant ability, which he discovers through the animals, is the power to convey deep emotion and even healing through his sound, transforming his playing from merely correct to truly expressive.
