Gamelan is characteristic of classical Indonesian music. 31-tone music, by contrast, is a typically Dutch invention that has been developed here. The 31-tone tuning of the Fokker organ offers possibilities for rendering exotic melodies and harmonies, similar to those used in the various types of gamelan. For example, the fifth can be divided into three, resulting in a Balinese scale with 6/5 seconds. These sounds align closely with the pelog and slendro tunings of metallophones, gongs, and drums that make up the Balinese and Javanese gamelan ensembles. Percussionists Robbert van Hulzen and Clara de Mik, both specialists in gamelan performance, will accompany Ere Lievonen (Fokker organ) during this remarkable concert. The result will be a melting pot of exotic sounds.
