By using 31 tones per octave instead of the usual 12, the repertoire of the Fokker organ can be considered contrary or unconventional. To provide an overview of these contrasting sounds, this programme presents a selection of diverse compositions that illustrate the rich musical literature of the Fokker organ. Alongside several old and contemporary classics, including a work by the American/Flemish composer Bert Van Herck, newly composed pieces written specifically for the Fokker organ by Miranda Driessen and Angus Barnacle will also be performed. Both of these composers have previously created works exploring such contrary sounds.
