As you can see from the chart above that for every octave you go up, you double the frequency - and it is the same in reverse; for every octave that you go down, you halve the frequency. The relationships between pitch and frequency are clearly evident in the chart.

 

Example: C4 is 261.63 Hz. To get to C5 we double the frequency so it is now 523.25Hz. And if we wanted to go from C4 to C3, it would be 130.81 Hz.

Now let us create the tag for this whole sound thing.

I always imagine a wave as a three dimensional entity, and with that I attach colours, speed and size. So, for a low frequency wave I will think of it as a large and flowing wave with nice warm colours like orange or deep red, and the whole image is nice and slow. For higher frequencies I use smaller and faster waves with harder colours like bright yellow or striking blue. This image is then enhanced further by having a person standing in front of the waves, usually me, but my name is Hertz and I am listening to these waves in a rental car. Although this may now confirm the urgency for me to seek therapeutic help, it is the best way for me to remember things.
