<u>Answer:</u> Option C
<u>Explanation:</u>
A musical interval between two notes or between one musical pitch and another with double its frequency, is called an octave. Like A3 to A4 is the interval of one octave. It is a natural mechanism popular as the "basic miracle of music" its application is well spread in most of the musical systems. The pitch in one or more than one octave can be calculated as follows:
For an instance, if one note has a frequency of 440 Hz
- One octave above has a pitch: 2 × 440 Hz = 880 Hz (A5).
- The frequency of two octaves above is: 2 x 880 Hz = 1760 Hz (A6).
- The note one octave below is at 220 Hz
- The ratio of frequencies of two notes an octave apart is hence 2:1.
