Knowledge and specialy Inspiration I got that time e.g. through the eccentric Konrad Boehmer, from wich I had Music History at the Royal Conservatory in The Hague.
Also Lucy van Dael did inspire me with retro-action, she gave authentic performance lessons at the Royal Conser- vatory in The Hague. She was concertmaster of the orchestra of the eighteenth century leaded by Frans Brüggen.
Followed at the time a masterclass with Sigiswald Kuijken at the Royal Conservatory in The Hague. How do you perform authentic Mozart sonates?... From then on I played more and more on the authentic manner.
