The Celle court organist Wolfgang Weßnitzer was a paragon of diligence when it came to compiling keyboard pieces. His collection, put together around 1662, is sure to impress the friends of early keyboard music and musicologists alike. It contains over 200 little pieces by Jan Pieterszoon Sweelinck and Heinrich Scheidemann – to name but the most famous composers – and was practically unknown until now. For our first edition, Martin Böcker has selected 32 previously unpublished pieces. The “Celler Clavierbuch” offers an impressive panorama of the rich and vibrant music that was written for the harpsichord, the spinet, the clavichord, etc. in Northern Germany in the mid 17th century.
