Anders about the project

Ever since I began studying percussion, I have become more and more interested in contemporary music and microtonality. I feel that microtonal instruments are a natural evolution of an ever- growing percussion section; hence, I think Kjell Tore's project is very interesting. There is no doubt that microtonal music is a part of today's and future music, so I feel almost obliged, as a musician, to be a part of it. It brings me much joy to work with the music of today, and to be a part of Kjell Tore's fascinating project.

Wendy Greenberg, second year masters student at the Norwegian Academy of Music. This video shows he rehearsing Farangis Nurulla-Khoja: the Unregenerate for extended marimba using some quartertones. The work was originally composed for Daniel Berg and an marimba "box" with quartertone extensions in 1997.

Wendy about the project

I have always been interested in exploring different avenues of music and percussion.  I jumped at  the opportunity to undertake an elective in quartertone marimba with Kjell Tore.  It is impossible to guess what the future will hold for Western art music but explorations such as Kjell Tore's  are surely helping its future development.
