Nettl Arapaho music includes ceremonial and secular songs, such as the ritualistic Sun Dance, performed in the summer when the various bands of the Arapaho people would come together. Arapaho traditional songs consist of two sections exhibiting terraced descent, with a range greater than an octave and scales between four and six tones. Other ceremonial songs were received in visions, or taught as part of a man's initiations into a society for his age group. Secular songs include a number of social dances, such as the triple meter round dances and songs to inspire warriors or recent exploits. There are also songs said to be taught by a guardian spirit, which should be sung only when the recipient is near death.
