ข้อมูลอนิเมะLa corda d'oro: primo passo

Episode one introduces the main characters, Lili and Kahoko Hino, and the Seiso Academy setting. Lili is a fairy involved with the school's music contest, the Intramural concours; Hino is a student who is chosen to enter the competition by Lili, despite not being a music student, because she is able to see Lili. Lili presents Hino with a magic violin, which can be played by any true lover of music. Another character introduced is Shoko Fuyumi, a first year student who is bullied by other music students because she was entered into the concours. When Hino defends Fuyumi, the music students challenge Hino to play, and she agrees to play before the concours in one week's time. Also introduced is Ryotaro Tsuchiura, when he accidentally bumped her and she nearly fell off the stairs, but catching her just in time.

Episode two introduces Len Tsukimori, a highly talented but very conceited second year music student. He is disdainful towards Hino and her friend Ryoutarou, a member of the Soccer Club, when they meet. Despite this, when she hears Tsukimori practicing the violin, she is greatly moved and give him great praise, which he haughtily dismisses. After hearing him play, Hino is able to recall the feelings and with the magic violin, she is able to play the piece, which Lili tells her is Schubert's Ave Maria. Hino also meets the friendly, outgoing third-year music student, Kazuki Hihara, on the rooftop. Hihara tries playing Gavotte, Hino's practice piece, on his trumpet, but Hino is puzzled that the melody sounds different from when she plays it.

Hino has decided to help Lili and practice hard. Hino rescues Tsukimori from being cornered by two other music students by splashing them with water from a vase; however, the vase breaks and cuts her fingers. Tsukimori shows concern, though ostensibly because this will affect the overall performance of the concours, and not on Hino's behalf. Later Tsukimori and Tsuchiura get into an altercation over Hino and music. Tsukimori informs Tsuchiura disdainfully that general education students have no right to say anything about music. Afterwards, Hino was informed that she needs an accompanist for the first selection. Then, Hino discovers Tsuchiura playing the piano beautifully in a music shop. When Tsuchiura notices Hino, he becomes upset and makes Hino promise not to tell anybody about it.

Hino seeks a piano accompanist, which proves difficult because she is a general education student. She is wary of an offer by Azuma Yunoki to find her an accompanist. Eventually another girl offers to accompany her and she accepts. She visits the shop after practice, where the manager offers to show her a video recording of a young prodigy, who turns out to be Tsuchiura. She is amazed at his piano playing, and is overwhelmed with emotion, which makes her cry. She laments that as a violinist, she cannot play Chopin’s pieces. The manager manages to find the score, Chopin's Allegro, for the violin. She makes up her mind to play this in the concours. Later, Hino encounters Tsuchiura, and on her request, he plays for her. When she tells him about the video she saw, the feelings about his playing, and her regret that he no longer plays the piano in public, Tsuchiura becomes upset and leaves but then regrets it.

On the day of the first selection, Hino turns up dressed informally through her ignorance. Thankfully, Lili shows up in her dressing room and uses magic to provide her with a selection of dresses. At one point, Hihara enters without knocking and sees her wearing a nun's habit. However, Lili quickly switches her back to the school uniform and Hino attempts to pass it off as "seeing things". A teacher then directs Hihara away from the girls’ dressing room. Hino and Lili eventually choose a knee-length white dress. During the performance, Hino's accompanist ducks out, criticizing Hino's lack of commitment to music practice. Tsukimori arrives at the scene and defends Hino, while her accompanist runs away crying. Hino goes on without accompaniment; after a few notes, she is asked to leave the stage because all participants are required to have an accompaniment. Tsuchiura steps forward from the audience and takes the place of Hino's accompaniment. Tsuchiura tells Hino to forget their arguments, and the two take the stage. Hino plays Chopin's Tristesse, or "song of parting" but she feels that it is not an ending, but a beginning, during the performance; Tsuchiura admires Hino and her way of performing. Everybody, even the judges, remarks on how joyful and vibrant the piece sounds when Hino plays it. The concourse members, too, are overcome with emotion. Then Tsukimori goes on and gives a powerful performance. In the end, Hino comes last in the selection and Tsukimori comes first.

After the first selection, Tsuchiura was added to the participants for the concourse. All the seven participants including Kanazawa went Fuyumi's family villa for four days and three nights. Hino apologizes to Tsuchiura about him being in the concours and he rubs her head and says that its alright and she begins to blush. After a night of sharing a room with each other, i.e Tsukimori and Tsuchiura, they immediately demanded Kanazawa to change their rooms. So,Len is with Azuma and Ryotaro gets a room with Kazuki and Shimizu. Hihara is shown for the first time as being serious in his huge crush on Kahoko, which comes out when he falls on her by accident. He also is shown as someone who thinks of girls as very different from guys....'smell like sunshine and butterflies" to be exact and Tsuchiura gets irritated when that happened.

Kanazawa asks Hino to come with them shopping for food and souvenirs, leaving Tsuchiura, Hihara, Yunoki and Tsukimori at home. Kanazawa left a note saying that they can pre-heat the food for lunch. Unfortunately, Tsukimori burnt the food thus having Tsuchiura make lunch. After the dinner, Tsukimori fell asleep. When he woke up, he heard Hino playing and he made a duet with her. Upon returning to school, Tsukimori is chased by school newspaper reporter Nami Amou. He stumbles upon Hino who just finished practicing her violin and covers her mouth when Amou's voice is heard just outside and after she passes, he releases his cover over her mouth prompting her to leave. While walking away, Hino comments on how she felt Tsukimori's cold hand before and this time it was hot with a burning feeling, realizing what's happened she runs back to the practice room to discover Tsukimori leaning against the wall almost unconscious. As she is about to call for a doctor Tsukimori stops her and losing complete conscious his head falls on her shoulder.

The second selection is coming close and Hino still hasn't decide what song she will play. Being stressed like she is, practicing violin every time she has the chance causes her to be in a fight with her friends. At home, Hino accidentally broke her music box, which was a birthday present from Mio and Nao which played Pachelbel’s Canon. After fixing her music box and reconciling with her friends, Hino decides to play the Canon for the second selection.

Hino is having problem with her performance because she thinks that her performance is not good enough. Tsuchiura advises her that she can perform in a public place to have more confidence. The next day, Hino goes to practice outside but Amou sees her and Fuyumi. Amou helps the both of them to choose the clothes for the upcoming selection. When she is going back home, she meets Manami, the owner of the music shop; he tells her about a concert so she goes to watch it. There she meets Shimizu and they watch the concert together. They also get to meet the players. Hino is asked to play her violin. Then Hino played Ave Maria for them.
