New recordings which have the field almost to themselves in an overlooked corner of Buxtehude’s output.

‘One of the world’s most prolific harpsichordists’ (Gramophone), Pieter-Jan Belder now leads this comprehensive and often revelatory survey of the surviving chamber music by Dieterich Buxtehude. Comprising eight musicians active on the Dutch early-music scene, Ensemble Fantasticus presents the only complete set of this music on record, making it an essential acquisition for all Baroque-music enthusiasts, further enhanced by detailed notes on both composer and works by Jon Baxendale.

Buxtehude became the Cantor of the Marienkirche in Lübeck in 1668, at the age of 31. This would be his last church post. Bach undertook his famous journey by foot to Lübeck in 1705 – 37 years later – indicating the longevity of Buxtehude’s career. His duties required him to focus on writing music for the church, and only latterly did he turn to chamber music (much in the way that Bach did during his last decade). The seven sonatas of Op.1 were published in 1694, and Op.2 appeared two years later; these collections represent the only known examples of his music printed during his lifetime.

Buxtehude seems to have regarded the two collections as a unity, which emerges from study of their instrumentation and key structure. Seven might also be significant since it represents the number of notes in the diatonic scale and is also a number steeped in mysticism and symbolism. It also symbolises the humours of the seven planets, which Buxtehude is reputed to have described musically when encountering the astronomical clock at the Marienkirche.

Considered together, the 14 sonatas (all scored for one or two solo instruments plus continuo, with strings in mind) open up an unparalleled universe of rhetorical expression that never fails to surprise or move the listener. The collection also includes unpublished pieces which round out our grasp of Buxtehude as an instrumental composer: a further 10 sonatas, not easy to date within the composer’s career, but full of striking ideas such as the ground-bass passacaglia underpinning an A minor Trio Sonata.
