The twelve-part work helped earn him a reputation for writing some of the longest piano music ever composed. That reputation needs a qualification: it was described as the longest non-repetitive piano work for many years, but the available sources do not establish a current world record.
Who was Kaikhosru Shapurji Sorabji?
Sorabji was born in Chingford, Essex, in 1892. His father was a Zoroastrian Parsi civil engineer, and his mother was English; the Sorabji Archive says an older account describing her as partly Spanish and Sicilian was mistaken. Calling Sorabji a Parsi composer reflects his paternal family background, while he was English by birth and life.
Largely privately educated and intensely private, Sorabji worked not only as a composer and pianist but also as a writer and music critic, contributing to The New Age and The New English Weekly. The Archive records more than 100 completed works between 1915 and 1984. His output ranged from short piano miniatures to immense scores, and included vocal, chamber and orchestral music as well as works for solo piano. The Sorabji Archive’s biography provides further biographical detail.
How long is Opus clavicembalisticum?
Composed in 1929–30, Opus clavicembalisticum is a twelve-part piano work running to 253 pages. Marc-André Roberge gives its duration as about four and a half hours. Performance time varies: the Archive recounts pianist John Ogdon’s account as lasting four and three-quarter hours.
The scale is not just a matter of duration. Roberge describes a passacaglia of roughly 40 minutes containing 81 variations, followed by a roughly 40-minute quadruple fugue. The structure combines enormous formal ambition with a demand for sustained concentration from both performer and listener. Roberge’s account of the work gives more detail on its design.
Was Sorabji’s work the longest piano piece ever written?
Opus clavicembalisticum has a notable historical claim, not a securely established present-day title. A Naxos booklet says it was acknowledged “for many years” as the world’s longest non-repetitive piano work. That phrasing is narrower than “the longest piano piece ever”: it refers to a historical reputation and excludes repetitive works. The sources available here do not provide a comprehensive current ranking of piano works, so it would be misleading to present Sorabji’s piece as today’s confirmed record-holder. The Naxos booklet discusses the work’s place in recording history.

How large was Sorabji’s wider musical output?
The extraordinary length of Opus clavicembalisticum is one part of a much larger body of work. Catalog totals differ because they come from different dates and catalog scopes:
| Source and date | Catalog count | Page total |
|---|---|---|
| Marc-André Roberge, 2000 | 111 works | More than 11,000 manuscript pages |
| Sorabji Resource Site, page marked modified January 1, 2026 | 116 catalogued works | 11,503 pages in its index |
These are not competing measurements of an identical, fixed list. The Resource Site’s index sorts catalogued works by score page count and excludes four separate piano parts from its summary; Roberge’s figures were published earlier. The contrast gives a sense of the output’s scale without implying that every work is a piano solo or that page count directly predicts playing time. The Archive describes the broader catalog and Sorabji’s works; the Resource Site page index explains its page-count listing.

Sorabji also wrote shorter pieces, and his piano music was only one part of his output.
What does Sorabji’s music sound like?
His piano writing draws on Romantic and post-Romantic keyboard language while often expanding it into elaborate, highly ornamental textures. That description points to a music of dense detail and extended development rather than a single style or mood; Sorabji’s catalog covers a wide range of forms and scale.
Some works also reflect literary and cultural inspirations. Roberge identifies Persian poetry as an inspiration for Le jardin parfumé, Nocturne: Jami and Gulistan: Nocturne for Piano. Those titles and influences offer a route into works beyond the most famous giant score.

After his last concert appearance in 1936, Sorabji required his consent for public performances. The Archive cautions that this was not an unequivocal blanket ban, although it helped make performances rare for nearly four decades. Sorabji considered his works unsuited to conventional concert performance and wrote, as reported by the Archive, that “no performance at all is vastly preferable to an obscene travesty.”

Interest revived from 1976, when pianist Yonty Solomon’s recitals helped bring the music back to audiences. Later authorised performances and recordings challenged the idea that Sorabji’s work was simply unplayable. Ogdon’s performance of Opus clavicembalisticum in the 1980s, lasting four and three-quarter hours, became one of the landmark accounts of the piece.
The Archive lists performers and broadcasters including Yonty Solomon, John Ogdon, Marc-André Hamelin, Michael Habermann, Donna Amato, Ronald Stevenson, Geoffrey Douglas Madge, Carlo Grante, Charles Hopkins and Jonathan Powell. To hear the music, look for a recording of Opus clavicembalisticum and check its performer, duration, completeness and format: timings differ among recordings and performances. The Archive also issues copies of scores and writings to the public worldwide; availability can be checked directly with the Sorabji Archive.
