Musaf is the final part of the Yom Kippur morning prayer service. The Amidah contains the confessional. The repetition of the Amidah includes piyyutim (poems), selichot (penitential prayers), and the confessional. The Yom Kippur Musaf service consists of two parts: the Avodah (description of the Yom Kippur prayers and rituals during the time of the Temple) and the Martyrology (description of the murders of ten talmudic sages tortured by the Romans). Musaf ends with the hymn "Ha'yom Te'amtzaynu" (This day shalt thou strengthen us).
A short break is usually taken between musaf and mincha.
