Jonny Greenwood: Radiohead Guitarist and Oscar-Nominated Composer

The table below compiles the core biographical and career details that appear throughout this article.

Is Jonny Greenwood a genius?

Critical acclaim

• Director Paul Thomas Anderson has called Greenwood “a genius” in interviews (NPR (public radio)).
• Thom Yorke credited Greenwood as “the reason we sound the way we do” (NME (music magazine)).
• David Bowie, in a 1995 interview, described Radiohead as “a collective” rather than a band, implicitly acknowledging Greenwood’s unusual role.

The pattern: the label “genius” follows Greenwood not just from fans but from the most respected voices in music and film. But the word itself is subjective – what matters is the consistent recognition of his originality.

Musical innovations

• Greenwood pioneered the use of the ondes Martenot, an early electronic instrument, in rock music – most notably on Kid A and Amnesiac.
• He also developed a signature guitar style that blends atonal effects with melodic lines, often using custom-built effects pedals.
• His score for There Will Be Blood partly derived from the piece Popcorn Superhet Receiver, a classical composition he wrote for the BBC (Faber Music (publisher)).

The catch: Greenwood’s innovations aren’t just technical tricks – they’re structural. He treats a film score as a compositional puzzle, not background music.

Film scoring achievements

• Greenwood has scored films for Paul Thomas Anderson, Jane Campion, Lynne Ramsay, and Pablo Larraín (IMDb (film database)).
• He received Academy Award nominations for Phantom Thread (2018) and The Power of the Dog (2022) (IMDb Awards (awards database)).
• He won the Critics’ Choice Movie Award for Best Score for There Will Be Blood (AlloCiné (film database)).
• He also received a British Independent Film Award for Best Music for You Were Never Really Here (IMDb Awards (awards database)).

Which Radiohead songs did Jonny Greenwood write?

Notable songs written or co-written

• Greenwood is credited as a co-writer on many Radiohead tracks, including “Everything in Its Right Place”, “Idioteque”, and “The National Anthem” (Wikipedia (encyclopedia)).
• He also contributed to “Pyramid Song”, “Knives Out”, and “Weird Fishes/Arpeggi”.
• His songwriting credits often involve the electronic and experimental elements that define Radiohead’s later albums.

What this means: Greenwood’s role in Radiohead goes far beyond lead guitar – he is a primary architect of the band’s sound, especially on the electronic-heavy albums Kid A and Amnesiac.

Songwriting credits on Radiohead albums

• On Kid A (2000), Greenwood co-wrote the title track, “The National Anthem”, “How to Disappear Completely”, and “Idioteque”.
• On In Rainbows (2007), he co-wrote “Reckoner”, “House of Cards”, and “Jigsaw Falling into Place”.
• His contributions are often the most sonically adventurous – the glitchy beats, the ondes Martenot, the string arrangements.

The trade-off: Greenwood’s experimental instincts sometimes push the band into challenging territory, but that risk-taking is exactly what has kept Radiohead relevant for three decades.

Did Jonny Greenwood not know how to play keyboard?

Early lack of keyboard skills

• According to interviews, Greenwood initially did not play keyboard and was primarily a guitarist when Radiohead formed.
• He taught himself keyboard specifically for the recording of Kid A (2000), because the band wanted to incorporate electronic sounds (NPR (public radio)).
• This self-taught approach gave his keyboard parts a raw, unconventional quality that became a hallmark of the album.

The pattern: Greenwood’s lack of formal training wasn’t a limitation – it was a feature. He approached the keyboard with a guitarist’s mindset, creating unusual chord progressions and textures.

Transition to multi-instrumentalist

• Since Kid A, Greenwood has become a multi-instrumentalist, playing keyboards, piano, synthesizers, and the ondes Martenot.
• He also plays the viola, cello, and other string instruments, often incorporating them into his film scores.
• His ability to switch between instruments has made him one of the most versatile musicians in contemporary rock.

The implication: what started as a necessity – learning keyboard to create electronic music – turned into a defining skill that set Greenwood apart from most rock guitarists.

Was Jonny Greenwood in Harry Potter?

Role in Harry Potter and the Goblet of Fire

• Yes, Jonny Greenwood appeared as a member of the Weird Sisters in Harry Potter and the Goblet of Fire (2005).
• He played guitar in the band alongside other Radiohead and musician cameos.
• The scene was a brief but memorable appearance during the Yule Ball sequence.

The catch: it’s a minor cameo, but it’s a fun trivia point that connects Greenwood to the Harry Potter universe.

Other film appearances

• Greenwood has also appeared in other films as a musician, such as in Bodysong (2003) and The Master (2012) in small roles.
• He is primarily known for his work behind the camera as a composer, not as an actor.

The pattern: Greenwood’s cameos are rare and usually tied to his music – he’s not pursuing an acting career.

Which Radiohead member is married to an Israeli?

Who is Sharona Katan?

• Sharona Katan is an Israeli artist.
• She and Jonny Greenwood married in 2004 (Wikipedia (encyclopedia)).
• The couple have three children together.

The implication: Greenwood’s marriage to an Israeli artist has been a stable part of his personal life, though he keeps his family relatively private.

Marriage and family

• Greenwood and Katan live in London.
• He has spoken in interviews about the importance of family grounding his life, especially amidst the chaos of touring and film scoring.
• His children have occasionally been mentioned in interviews, but he rarely shares details publicly.

The trade-off: Greenwood’s private family life contrasts with his very public career, but that boundary may be key to his creative longevity.

“Jonny is the reason we sound the way we do.”

— Thom Yorke, Radiohead lead singer (NME (music magazine))

“He’s a genius. I don’t use that word lightly.”

— Paul Thomas Anderson, filmmaker (NPR (public radio))

“They are not a band, they are a collective.”

— David Bowie, 1995 interview (attributed)

Greenwood’s career is a rare case of one musician excelling in two demanding worlds. For Radiohead fans, he’s the experimental edge that keeps the band surprising. For film lovers, he’s one of the most distinctive composers working today. The dual career isn’t without challenges – balancing tour schedules with scoring deadlines, constantly shifting between rock and orchestral modes – but Greenwood has made it look seamless. For anyone wondering whether a rock guitarist can become a serious film composer, the answer is already written in the scores.
