If you want to take active part in the developments of microtonality, then it is possibly a good idea to consider a membership. The Dutch Microtonal Society is open for all people, interested in microtonal music, for listeners, as well as for musicians, composers and musicologists. There are no terms to become a member. The membership costs just a small amount of €10,- a year, outside Europe $14,- a year. This sum can be transfered to account number , att Stichting Vrienden van de St. Huygens-Fokker, located in Amsterdam, indicating 'Society'.
If twelve tones are not enough for you too, but you rather support ‘another sound’ only financially, then we advise you to become a contributor to the Huygens-Fokker Foundation.
