-The '''hexatone''', 531441/262144, is the interval found by stacking six (Pythagorean whole) [[tone]]s ([[9/8]]). The Medieval music theorist Jacobus of Liège described it along with the [[ditone]], [[tritone]], [[tetratone]], and [[pentatone]], and noted that the hexatone was a rough discord, not equivalent to a pure octave;<ref>http://www.medieval.org/emfaq/harmony/pyth4.html</ref> it is wider than the octave by one [[Pythagorean comma]].
