Q:

the frequency of A4 is 440.00 Hz.what is the frequency of A6, which is two octaves above A4?

Accepted Solution

A:
To solve this problem you must apply the proccedure shown below:

 1. You have the following information given in the problem above: The frequency of A4 is 440.00 Hz.

 2. So, you must apply the following formula to calculate the frequency of A6, which is two octaves above:

 (2^n)f

 Where n is the octaves above and f is the known frequency.

 3. Therefore, you have:

 A6=(2^n)f
 A6=(2^2)(440.00 Hz)
 A6=1760 Hz

 Therefore, the answer is: A6=1760 Hz.
