Quartet for Oboe and String Trio

Rautavaara moved to dodecaphony in the orchestral works Praevariata and Modificata. In chamber music the first work in this period is the Oboe Quartet (1957/1964). It includes material that Rautavaara intended for a string trio he was working on during his studies in New York, but eventually never completed. He also used this material in Modificata.
