Sunstructure
1982 (12′)
Orchestral music
‘Sunstructure’ corresponds to the authentic sun structure, recorded on photographic material by the solar telescope near Westerbork (NL). The data of measurement were then transposed by the observatory in Utrecht by means of computers in the audible frequency range (7 octaves), resolution rate half intervals, tempered tuning. For more Information see Sonnenmusik .
Kurt Dahlke arranged the electronic composition ‘Sunstructure’ for the ‘Sunwheel’ project. It was presented in Lelystad on August 7th, 1992 (6 pm) and in Massada on September 25th, 1994 (6.10 pm). The editing of ‘Sunstructure’ uses two different methods. On the one hand, individual solar frequencies are released from their overall context and assigned an independent musical function such as motif or melody, on the other hand, the frequencies of the solar structure as a whole are transposed to musical scales, restoring direct Earth-relatedness.
This electronic compostiton is on the CD Sunwheel.
