in the western music tradition there are twelve notes defining one octave, other systems have more or less notes to an octave, some even have different amounts of individual notes in a scale depending on whether you are moving up or down the scale. the Eight notes you speak of belong to the major and minor scales of the western tradition (greek name that i've forgotten sorry), where a series of notes are drawn from the 12 frequency divisions of the octave, making a Key.
