   octave
   to modern ears, the 'same' pitch separated by register. The octave is the eighth note counting by step up a diatonic scale and in modern notation would be called by the same letter name as the starting pitch. Medieval listeners, however, did not consider octaves to be equivalent, so, for instance, a cadence on the upper octave could not be substituted for a lower note. See interval.
