In music, an octave is the distance between one musical note and the next note with the same name but higher or lower — like from one 'Do' to the next 'Do.' It's the interval you get when a sound wave's frequency doubles. People also use 'octave' loosely to describe how high or low a voice sounds, like 'her voice went up an octave' when someone gets or scared.
