Eben continued during his lifetime to develop the style of music in which he wrote. He was interested in Czech folk music and he wrote down many folk songs that he heard in Moravia. He listened to plainchant in church music. All this helped him to develop his own style of composition. He is best-known abroad for his organ music, especially works such as "Musica Dominicalis" ("Sunday Music") which includes a popular piece called "Moto Ostinato". Other organ works include "Faust" (1980), "Job" (1987) and "A Festive Voluntary" which is a set of variations on the tune of "Good King Wenceslas", written for the reopening in 1986 of the organ at Chichester Cathedral which had just been restored. He also wrote a lot of music for orchestra as well as chamber music. He composed some beautiful music for children’s choir, including church music called "Liturgical Songs".
