Dispokinesis was developed more than 45 years ago in the environment of the Sweelinck-Conservatory, Amsterdam.
Contemporaries nicknamed him Orpheus of Amsterdam and even the city authorities frequently brought important visitors to hear Sweelinck's improvisations.
Bernhard and Gould never met in real life; however, Gould did play twice in Salzburg: the Bach D Minor Concerto with Mitropoulos on 10 August 1958, and a Sweelinck-Schoenberg-Mozart-Bach recital on 25 August 1959.
