The Quadrat Prints are experiments on graphic art and design, fine arts, literature and architecture.

1. cover design (The Quadrat Prints: Music and Technics, 1960)
2. traces of the resonant past: Wakamba Dancers from Kenya
3. the instrument as an extension-piece of the human body: the contra-bassoon, and the machine, obeying only to the human mind, scheme of a sawtooth generator
4. the recording of sound itself by way of electronics, through today's tape recorder
5. electronic apparatus explore sound and can picture the single tone: oscillograph with sinus-symbol, or registering of complex sound
6. spectrogram of a fragment, lasting over six seconds, from Study II by Karlheinz Stockhausen
7. the existing method of notation proves to be inadequate for electronical music. An example of the search for an adequate notation-method shows us the score-page from Study II by Karlheinz Stockhausen
8. The first public manifestation of electronic music in the Netherlands took place at Bilthoven, under the auspices of the Institution Gaudeamus in August 1956. An electronical concert followed in Oktober 1957 at Philips' Schouwburg Eindhoven; surroundings and formation of the audience clearly show an inclination towards the musical past
