The compositions of Lukas Foss illustrate two main periods in his artistic development, separated by a transitional phase, which is characterized by controlled improvisation. The works of the first period are predominantly neo-classic and eclectic in style, which he infused with elements of American popularism. The transitional period began in 1956 when he began to formulate what he referred to as "system and chance music" for his work with the Improvisation Chamber Ensemble. This led to an abandonment of tonality and the classical fixed forms in favor of serialism, indeterminacy and graphic notation. ~ Stephen Kingsbury, Rovi
