During the twentieth century, the organ experienced a resurgence of interest. Music from the 16th and 17th centuries was rediscovered, modern composers began to arrange favorite hymn tunes with newer harmonic structures and rhythmic possibilities, and new music was composed that has a contemporary feel. Organ settings were written by contemporary composers and arrangers for new hymns and some contemporary worship songs.
