In the collection "Songs With Piano Accompaniment" (שירים בליווי פסנתר) he applied Gregorian modes to Israeli folk music.
He wrote the cantata "A Day Will Come" (עוד יבוא יום) to a poem by the Labor Zionist ideologue A. D. Gordon.
In 1948 the Jerusalem Symphony Orchestra performed his overture based on the melody of the traditional Hanukkah song Ma'oz Tzur.
