In the long history of film and television music, it is unusual for a composer working in a single medium — particularly a medium as commercially constrained and as aesthetically complex as Japanese television animation — to produce a body of work whose range, ambition, and consistent quality places them in the company of the finest composers in any medium. In the history of anime music, this distinction belongs to two individuals whose careers have run in partial parallel across the past three decades and whose work defines the ceiling of what anime scoring can achieve: Yoko Kanno (菅野よう子) and Yuki Kajiura (梶浦由記).
These two composers are not the only significant figures in anime music — I described the broader anime music landscape in earlier articles — but they are the figures whose specific achievements most directly address the question of whether anime can be scored at the level of serious concert music, and whose answers to that question are the most unambiguous yes available. Understanding their work is understanding both what anime music can be and what the specific demands and freedoms of the anime scoring context have produced in two extraordinarily talented composers who chose it as their primary creative medium.
Yoko Kanno: The Polymathic Voice
Yoko Kanno was born in 1963 in Miyagi Prefecture and developed as a musician through classical training before moving into commercial music in the late 1980s. Her early commercial work — the scores for video games including the Nobunaga’s Ambition series and the early-career advertising music she produced — demonstrated the specific range that would characterise her mature work: the ability to work fluently across musical styles, genres, and historical periods, producing music that is convincingly within each tradition it references while remaining identifiably her own.
The specific collaborative relationship with the director Shinichiro Watanabe that produced Kanno’s most celebrated work is one of the most productive director-composer relationships in any animated medium. Watanabe’s specific approach to music — treating it as an equal narrative element rather than as emotional support for the visual storytelling — created the specific freedom that Kanno’s range required: the freedom to compose music whose relationship to the on-screen action was interpretive and expressive rather than illustrative and subservient.
Cowboy Bebop (1998). The score for Cowboy Bebop is the specific work most consistently cited by music critics, anime critics, and fellow composers as the finest anime music ever produced, and the claim is difficult to dispute on its own terms. The score encompasses jazz (bebop, cool jazz, hard bop), blues, rock, country, operatic pieces, ambient electronic music, and various hybrid forms that combine these traditions with a naturalness that suggests deep internalization of each tradition rather than mere stylistic quotation. The specific tracks most cited as evidence of the score’s quality:
Tank!, the series’ opening theme, is a piece of big-band swing whose horn arrangement and rhythmic drive represent a command of jazz orchestration that would be impressive from a specialist jazz composer. The specific quality of the brass writing — the voicing, the articulation, the rhythmic density — reflects firsthand knowledge of the idiom rather than the competent simulation that a non-specialist might produce. Green Bird, the haunting vocal piece that accompanies the series’ most emotionally devastating sequences, is built on a wordless soprano performance over a sparse, harmonically ambiguous accompaniment whose emotional effect depends on the specific restraint with which it builds and releases tension. Space Lion, the blues elegy that closes one of the series’ most important character episodes, is a piece whose specific emotional weight — the specific way the harmonica and guitar textures accumulate into something genuinely mournful rather than merely sad — exceeds what the visual storytelling alone could achieve.
Ghost in the Shell: Stand Alone Complex (2002-2005). The score for Stand Alone Complex demonstrates Kanno’s range in a different direction from Cowboy Bebop — where Bebop required the range of American popular music genres, the Stand Alone Complex score required the specific textures of electronic music, industrial sound design, and the specific fusion of electronic and acoustic traditions that the series’ cyberpunk aesthetic demanded. The opening theme Inner Universe — whose vocal text is a fusion of Russian, Latin, and English over a drum-and-bass foundation with live string writing — is a piece that several critics have identified as not merely the finest opening theme in anime history but one of the most arresting pieces of commercial music composed in the early 2000s.
The collaboration dynamic. One of the specific characteristics of Kanno’s working method that is widely discussed within the anime production community is her tendency to compose music during or before the animation process rather than after — delivering music tracks to the production that the animators then cut to, reversing the standard post-production scoring process. This inversion produces a specific quality in the finished work: the visual and musical elements are often in a genuine dialogue rather than the music simply following and amplifying the visual, because the animation was created in response to the music’s emotional suggestions rather than the music being fitted to the animation’s predetermined emotional contours.
Yuki Kajiura: Architecture of Emotion
Yuki Kajiura was born in 1965 in Tokyo and developed her musical approach through a background in classical piano and through her work in the pop-rock group See-Saw in the late 1990s. Her anime scoring career began in 2001 with the score for .hack//SIGN and developed through a sustained series of major productions that has made her the most consistently commercially successful anime composer of her generation.
The Kajiura aesthetic: where Kanno’s specific quality is range — the ability to move convincingly across an extraordinary variety of musical traditions — Kajiura’s specific quality is depth and architectural consistency. The Kajiura sound is immediately recognisable across all her productions: the specific combination of choral and solo female vocals in an invented language (Kajiurese — the wordless syllables she uses when the emotional effect of vocal performance is desired without the semantic content of real language), the dense string writing whose specific harmonic language is her most personal contribution to the scoring vocabulary, and the specific emotional quality of her melodic writing — the particular melancholy, the specific grandeur, the specific quality of reaching toward something transcendent while remaining aware of the costs involved.
Puella Magi Madoka Magica (2011). The score for Madoka Magica is the specific work most directly responsible for Kajiura’s international recognition, and its achievement — the specific alignment of the music’s emotional content with the series’ specific themes — demonstrates the composer’s ability to work in precise dramatic partnership with a specific creative vision. The series’ specific deconstruction of the magical girl genre required a score whose beauty was inseparable from its menace, whose grandeur was always in tension with its tragedy — and Kajiura delivered this specific emotional complexity in a body of work that the series’ millions of international viewers frequently identify as the aspect of the production whose quality most exceeded their expectations.
The specific tracks most cited: Credens Justitiam, the transformation theme that deliberately echoes the triumphant orchestral tradition of the conventional magical girl score while introducing specific harmonic shadows that undermine the triumph; Decretum, the haunting choir piece that accompanies several of the series’ most devastating revelations; and Surgam Identidem (loosely “I rise again”), the piece whose specific quality of determined melancholy becomes, in the context of the narrative, one of the most emotionally complex musical experiences available in television anime.
Sword Art Online (2012-present). The Sword Art Online score is Kajiura’s most commercially successful anime composition work, and its specific production over multiple seasons demonstrates the specific challenge and the specific achievement of sustaining a musical identity across many years of production. The initial SAO score’s specific mixture of epic orchestral action writing with the intimate character pieces that accompany the series’ emotional moments produced a commercial template that subsequent seasons have maintained with varying success, but the original season’s specific quality — the specific investment of the opening episodes’ music in establishing the emotional stakes of the series — remains the work’s compositional foundation.
The Composer’s Process: How Anime Music Is Made
The specific process by which anime scores are produced differs significantly from the film scoring process in Western cinema, and understanding the differences illuminates both the constraints and the specific creative opportunities that anime scoring presents.
The storyboard-based scoring approach: most anime scores are composed from storyboards (絵コンテ — ekonte, the shot-by-shot visual plan of each episode) rather than from completed animation, because the production schedule’s constraints mean that the composer must deliver music before the animation is finished. This process requires the composer to interpret the storyboard’s visual intentions in musical terms — to understand from the preliminary drawings what emotional content the sequence will carry, and to compose music that serves that emotional content without the full visual information that the final animation will provide. The specific skill this requires — the ability to read visual intention from rough drawings — is a specialist competence that the experienced anime composer develops through repeated practice with the medium.
The music library approach: many anime productions build a library of thirty to sixty musical pieces for a series rather than composing specific cues for specific scenes, and the music editor (音楽担当 — ongaku tantō) selects appropriate pieces from the library for each scene during the sound editing process. This approach requires the composer to produce music that is simultaneously specific enough to have emotional character and general enough to serve multiple narrative contexts — a specific compositional challenge that differs significantly from the Hollywood approach of composing specific cues for specific scenes.
Both Kanno and Kajiura have worked within both the library approach and the more specific scene-specific composition approach, and both have commented on the specific different creative demands each method produces. Kanno has described the library approach as producing a specific freedom — the music is composed as music rather than as scoring for a specific visual sequence, which allows a specific kind of compositional integrity. Kajiura has described the scene-specific approach as producing a specific intimacy — the music for a specific scene is shaped by the specific emotional requirements of that moment, producing a specificity of emotional fit that the library approach cannot always achieve.
The Legacy: Influence on Anime Music
The specific influence of Kanno and Kajiura on the subsequent generation of anime composers is visible in the specific aesthetic choices of the composers who have emerged over the past fifteen years. The specific orchestral-electronic fusion that Kajiura pioneered has become a standard approach in the action anime genre, deployed by composers including Hiroyuki Sawano (whose Attack on Titan and Kill la Kill scores are the most commercially prominent expressions of this influence) and various others whose work acknowledges the Kajiura tradition while developing it in distinct directions. The specific genre fluidity that Kanno demonstrated — the willingness to compose genuinely within musical traditions rather than merely referencing them — has elevated the quality standard against which anime composers are now measured.
The specific international recognition that both composers have achieved — Kanno’s Grammy consideration for the Cowboy Bebop Remix album, Kajiura’s international tour with her FictionJunction concert project — reflects the extent to which the work they have produced within the anime scoring context has achieved recognition that transcends the medium. They have, in specific terms, demonstrated that the anime composer can be a significant artist, not merely a skilled craftsperson serving the commercial requirements of a specific genre.
