The term “clavis metrica” traditionally refers to a catalogue of poetic metres, poems written explicitly to explore shifting verse forms and demonstrate the virtuosity of the author. Inspired by ancient Icelandic poetry, Guðmundur Steinn Gunnarsson has composed his own musical clavis metrica. The metre provides a flexible canvas for musical composition that can withstand many variations in musical rhythm and melody, while still remaining recognisable to the trained poetic ear.

Guðmundur Steinn Gunnarsson is one of the pioneers of animated notation. His work is based on an intuitive exploration of organic rhythms that are not tied to a metronomic meter and that push the boundaries of traditional rhythmic concepts and notation.
