Sigiswald Kuijken was born in 1944 near Brussels. He studied violin at the conservatories of Bruges and Brussels, completing his studies at the latter institution with Maurice Raskin in 1964. He came into contact with early music at a very young age, together with his brother Wieland. Studying on his own, he gained a thorough knowledge of specific seventeenth- and eighteenth-century performance techniques and conventions of interpretation. This led to the introduction, in 1969, of a more authentic way of playing the violin, whereby the instrument was no longer held under the chin, but lay freely on the shoulder; this was to have a crucial influence on the approach to the violin repertoire and was consequently adopted by many players in the early 1970s. From 1964 to 1972, Sigiswald Kuijken was a member of the Brussels-based Alarius Ensemble (with Wieland Kuijken, Robert Kohnen and Janine Rubinlicht), which performed throughout Europe and in the United States. He subsequently undertook individual chamber-music projects with a number of Baroque music specialists, chief among whom were his brothers Wieland and Barthold, Gustav Leonhardt and Robert Kohnen, as well as Anner Bylsma, Frans Brüggen and René Jacobs. In 1972, with the encouragement of Deutsche Harmonia Mundi and Gustav Leonhardt, he founded the Baroque orchestra La Petite Bande, which since then has given innumerable concerts throughout Europe, Australia, South America, China and Japan, and has made many recordings for a number of labels.
