Canto Ostinato can be performed in a variety of combinations of keyboard instruments e.g. four pianos.
The composition finds its origin in a traditional source. It is tonal and uses functional harmonies. Although all parts have their own fixed place during the performance and cannot be exchanged, neither the beginning nor the end as limits of form, have any absolute significance.
Lemniscaat was first performed in Bergen N.H. in 1983 in the hall of an old cinema that was not used anymore and which was knocked down in later years. Without any furniture or interior decoration and the wooden floor boards in full view the hall looked like a ballet studio. The screen that was still there was used for showing colour slides: eighty more or less stylised images of the manuscript of the score that was used by the musicians were shown.
