Evryali (from Greek: Εὐρυάλη Euryale) is a piece for solo piano composed by Iannis Xenakis in 1973. It is based on a technique Xenakis invented in early 1970s, called arborescences—proliferations of melodic lines created from a generative contour (Harley 2004, 72). The title refers to the name of one of the Gorgon sisters, and is also Greek for open sea.
