"HELEN MACDOUGALL studied horn in Canberra, Australia, with Hector McDonald. After her graduation in 1991 she came to the Netherlands for postgraduate study, and has since then played freelance with all the symphony orchestras of the Dutch provinces and as first horn in the Netherlands Philharmonic Orchestra. Her specialisation is in the authentic performance practises of Baroque and Classical music using period instruments, for which she makes frequent tours throughout Europe with ensembles such as the Orchestra of the Eighteenth Century, Musiciens du Louvre, and Il Fondamento. Chamber music continues to play an important role for her on both early and modern instruments." (from

"Helen MacDougall studied horn at the School of Music of the Australian National University in Canberra, graduating with honours. She moved to Europe in 1992 to pursue her interests in researching and using authentic performance methods. Since then she has performed throughout the world with many of the famous early music ensembles of Europe, most notably as a regular member of the Orchestra of the Eighteenth Century (1993-2005) and Les Arts Florissants (from 2003). She has also played with La Petite Bande, Anima Eterna, Les Musiciens du Louvre, Freiburger Barockorchester, Akademie Alte Musik Berlin, Concerto Köln, Wiener Akademie, Il Fondamento, Il Complesso Barocco, Orchestra Libera Classica (Japan) and Pratum Integrum (Moscow), among others. With the latter she recorded Rosetti's Horn Concerto in d, released by Caro Mitis in 2005. As a chamber musician she has recorded with La Petite Bande and Nachtmusique. Helen has lectured or given master classes in Japan, Russia, Australia and Brazil, and was invited to lead the specialism "The Natural Horn in Modern Music" for the International Horn Society Symposium in La Chaux-de-Fonds in 2007. She also founded the Don Banks Trio which performs modern music (on valve horn) and has had many pieces specially written for it. Her main research interest is pinpointing the exact moment that hand-technique was introduced on the horn, through the early records of French and Belgian hunting-horn groups, and consulting with instrument makers to develop a more plausible reproduction of eighteenth century instruments."
