《Kitbull》是 Pixar 於 2019 年推出的動畫短片，由 Saschka Unseld 執導，講述一隻被遺棄的小貓與一隻受虐的小狗在城市相遇，建立深厚友誼並找到歸屬。影片以細膩的敘事與觸動人心的情感廣受好評，展現 Pixar 精湛的動畫技術，並傳遞關懷動物與珍惜情誼的訊息。

影片開場，小貓無意間撞倒瓶罐，滾動的瓶蓋吸引了牠的注意，最終滾向小狗的方向。音樂運用鋼琴的破碎音色呈現小貓的俏皮個性，旋律為 c-c-d-e-g-f#，並輔以弦樂與預置鋼琴增添層次感，模擬瓶蓋滾動的動態感。

隨著劇情發展，小貓與小狗開始玩耍，但小狗的吠叫嚇跑了小貓，隨後被主人趕出來。音樂以巴松管演奏狗的動機，並與貓的旋律對話，展現互動。當小狗試圖幫助受傷的小貓卻被誤會時，音樂由大調轉小調，節奏變慢，低音弦樂 pizzicato 營造猶豫與緊張感。

後續小貓關心受傷的小狗，兩者逐漸和解。音樂透過弦樂與鋼琴對話展現情感變化，弦樂旋律柔和，象徵修復關係。調性由小調轉為大調，拍號變化使音樂更具流動感與溫馨氛圍。

當主人出現，小貓鼓勵小狗逃離，最終成功逃出並被好心人收養。音樂節奏加快，低音弦樂 pizzicato 強化拍點，spiccato 與 piccolo 半音 trill 營造緊張感。結尾以長笛與巴松管演奏貓與狗的主題動機，回歸平靜，畫下溫暖的句點。

Kitbull

*Kitbull* is a 2019 Pixar animated short film directed by Saschka Unseld. The story follows an abandoned kitten and an abused puppy who meet in a city corner, forming a deep bond through mutual care and protection, eventually finding a sense of belonging. The film has received praise for its delicate storytelling and heartfelt emotions, showcasing Pixar's exceptional animation skills and conveying a message of animal welfare and the value of friendship.

At the beginning of the film, the kitten accidentally knocks over a bottle, and the rolling cap catches its attention, ultimately rolling towards the puppy. The music uses a broken piano sound to represent the kitten’s playful nature, with the melody being c-c-d-e-g-f#, accompanied by strings and preset piano to add depth, mimicking the dynamic motion of the bottle cap.

As the story progresses, the kitten and puppy begin to play, but the puppy’s barking scares the kitten, which is then kicked out by its owner. The music employs the bassoon to represent the puppy's motif, interacting with the kitten’s melody. When the puppy tries to help the injured kitten but is misunderstood, the music shifts from a major to a minor key, slowing down, with pizzicato bass strings creating a sense of hesitation and tension.

Later, the kitten shows concern for the injured puppy, and they gradually reconcile. The music features a dialogue between strings and piano, reflecting the emotional shift. The tonality moves from minor to major, and changes in time signature enhance the fluid and warm atmosphere.

When the owner appears, the kitten encourages the puppy to escape. The puppy eventually escapes and is adopted by a kind person. The music accelerates, with pizzicato bass strings accentuating the beats, while spiccato and piccolo trills create tension. The piece concludes with flute and bassoon playing the themes of the kitten and puppy, bringing the music back to a peaceful resolution, ending on a warm note.
