An '''Octave''' is an [[interval]] of eight (oct- means 8). It is used primarily in [[music]], because eight [[tones]] above the any [[pitch]] is another pitch that is interchangeble with it. This means the two notes sound the same although they're eight steps higher or lower.
Octave can also mean a group of eight.
