Through the piano pieces that comprise the Aulos series, Orbán introduces his students to the mysteries of polyphony in a direct and practical manner, and also makes them familiar with the art of composition. Those pieces have been brought to life here in the recordings made by pianist Márta Erdei.

''Márta Erdei intuitively understands György Orbán's pieces; in addition to their inventions and playful riots she also reveals their depths and underlying messages. The complex musical texture and all the hidden beauty of poliphony emerge in a crystal clear manner under her hands.'' (Ágnes Lakos)
