These natural rhythms, though constantly recurring, may appear largely incidental; yet there are elemental laws at work determining lyric rhythms, laws we must seek behind the poetic impulse. One law is that poetic art, as all other arts, shall be rooted fast in the physical surroundings which temper the race. Any effort to wrest an art from that traditional environment breaks it off at the tap root. NOTES 21. Burton, Frederick. American Primitive Music. Part II, p. 1. An interpretation. Moffat, Yard. N.
