Tephra (from Greek “ash”) refers to the material produced by volcanic eruptions, regardless of their size. It is structured in two interrelated movements: Litany in nomine Fibonacci and Hevel.Litany in nomine Fibonacci uses the Fibonacci number series and the golden ratio (closely related to it) to draw all musical material (melodic, rhythmic, formal…). This material is further organized in a fractal super-structure, full of symmetries that resemble biological forms. Hevel is a Hebrew word meaning “smoke” or, like tephra, “ash”. It’s also modelled after mathematical structures and shares with Litany in nomine Fibonacci many motives and rhythms, as well as a formal scheme inspired in biological forms.
