Barthold Kuijken is a Belgian flautist and recorder player, known for playing baroque music on historical instruments and particularly known for pioneering this manner of performance with his brothers, cellist and viol player Wieland Kuijken and violinist Sigiswald Kuijken, and the harpsichordist Gustav Leonhardt.
He studied the modern flute at the Bruges Conservatory and the Royal Conservatories of Brussels and The Hague. For playing early music he originally turned to the recorder. Research on authentic instruments, frequent collaboration with various flute and recorder makers, and assiduous study of sources of the 17th and 18th centuries helped him to specialize in the performance on original instruments.
For many years he played in the baroque orchestras Collegium Aureum and La Petite Bande. He plays chamber music concerts all over the world, extending his repertoire to early 19th-century music, and has recorded extensively.
He taught baroque flute at the Royal Conservatories of Brussels and The Hague, and in 2007 he became the first musician in Belgium to obtain the Doctorate in Arts (“Doctor in de Kunsten”) at the VUB (Free University of Brussels). His dissertation, which was later published as a book, was called, The Notation is not the Music – Reflections on more than 40 years intensive practice of Early Music.
Kuijken is also a sought-after conductor, and is currently the artistic director of the Indianapolis Baroque Orchestra.
