At the close of this speech the winds blew, the thunder rolled, the lightning flashed, and a terrible storm arose, amidst which the monster disappeared. The other returned to his people, told them the story of his travels, and to this day corn is sacrificed to the Missouri by the Gros Ventres to appease the spirit of the Wau-wau-kah. SONGS; MUSIC[60] [60] For the recording and interpretation of Siouan music see Miss Frances Densmore, Bull. 61, Bur. Amer. Ethn. The construction of the Indian flute and music produced by it have already been described, although we are not able to state in what manner, if any, it resembles the Arcadian pipe. Most ceremonies, dances, public demonstrations of joy or grief, and other matters of general interest are accompanied by songs, which have appropriate names, but these chants are for the most part only tunes or modulations of voices in concert, with the introduction of a few words in some of them. They are in fact a continued chorus consisting chiefly in repeating the meaningless syllables “Hai-yah, hai-yah, hai-ai-ai-yah-ah-ah, hai-yah, he-e-e-ah, hai-yah,” etc., fast or slow as required by the nature of the song. Where words are introduced they are composed of five or six syllables or three or four words, bearing some relation to the event which is honored with the song, but are of no consequence, so that all question regarding their rhyme or poetical compositions may be passed over in silence. The tune is generally begun by one person pitching it, who after singing a few notes, is joined by the whole choir, or sometimes, as in the scalp song, the women add their voices in the second part of the tune, where the name of the warrior who killed the enemy is mentioned. The modulations are bold and wild, by no means discordant or disagreeable, and they are remarkable for keeping very exact time either with the voice, drums, or feet, and where words are added they are so few, and the syllables so separated to accord as scarcely to be understood or distinguished from the rest of the chant.
