Sergiu Natra (b. 1924) is a Romanian-born composer who has resided in Israel for many years. He feels a strong affinity to the harp and has written an extensive amount of solo and chamber music for the harp. Prayer, from 1970, has been a required piece for several international harp competitions and remains popular among the harp community. It features Natra's signature style involving repeated motifs, alternating rhythmic and free sections, dissonant harmonies, and a wide variety of articulations.
