The concert etude Pattern Language was written in 2001, about 15 years after Julie-O was composed. Julie-O, a groundbreaking solo piece, written specifically for Turtle Island Quartet’s second recording, Metropolis, contains a number of non-traditional cello techniques adapted from the guitar and drums. In publishing Pattern Language, the intention is to use specifically composed etudes to shed light on some of these various passages, both to expand upon some of the techniques introduced in the piece, and to make Julie-O easier to play.
