Programme note
This work originated in 1984 at a time that the composer developed an interest in electronic keyboard instruments, especially in the wake of the technological (digital) developments.
During this time Roosenschoon was also very much concerned about the fact that very little was done to explore the possibilities inherent in the indigenous music of Southern Africa, and how this could be developed to enrich a culture that was predominantly Western. And although this was not his first piece in this particular direction, it nevertheless served as an important departure point from which many more African-oriented works of his followed
Although HELIOS contains sound elements that are clearly synonymous with Africa, it also displays Roosenschoon's fascination for sound colours, textures and exotic sound combinations. The sound patterns, be it fast or slow, were recorded on multi-track equipment which also has the advantage that the material, and the resultant "performance", can be controlled accurately.
The work is in an arch-type form with the two outer sections fast, with a slow and floating middle section.
