Guido of Arezzo or Guido D'Arezzo (991-1033) was a music theorist of the Medieval era. The invention of solfege is ascribed to Guido of Arezzo. He used a series of six syllables to refer to the six degrees of the hexachord. These six syllables were drawn from the hymn to Saint John "Ut queant laxis", because each of the six phrases of that hymn began on each of the six degrees of the hexachord: Ut queant laxis resonare fibris Mira gestorum famuli tuorum, Solve polluti labii reatum, Sancte Ioannes. This hymn gave the six acrophonic syllables: Ut, Re, Mi, Fa, Sol, La. In the course of time, "Ut" was changed to "Do" on the grounds that it was easier to sing, and the syllable "Si" was added to indicate the leading tone of the modern scale. About the artist: The Nairobi Trio consists of three gorillas (wearing derby hats and long overcoats) who mechanically mime to the music like wind-up toys. Like the way Obama mimes to the mantra of "Change", only without the derby hat. You drinkin' from the new Yogi's Kool-Aid?
