Thirty-One is the journal of the Huygens-Fokker Foundation, the Dutch centre for microtonal music. It is intended to be a forum for the Foundation’s central aims: to promote interest in and knowledge about microtonality in its broadest sense and in all its aspects. As a particular idiosyncrasy, the journal contains a greater-than-average focus on the system of 31-note equal temperament as explored in the mid-20th century by the Dutch scientist and musician Adriaan Daniël Fokker (1887-1972) following up the theoretical interests of the great sevententh-century scientist Christiaan Huygens.

The use of microtonal pitch materials in contemporary composition has expanded enormously in recent decades. Thirty-One welcomes and attempts to respond to that expansion of focus. We publish texts by and about composers, performers, theorists and instrument builders, hoping to reflect the multiplicity of viewpoints that underlie the usage of microtonality in theory and practice – indeed, even the usefulness of the term "microtonality" itself – a debate which, we hope, will resonate through future issues of this journal.
