Frequencies by 5ths
Below you can hear hear the first five partials in a harmonic series. These are the tones that are resonating inside any frequency. Here, they are represented as sine tones. Since tones don’t have these nested frequencies inside of them. So these frequencies are just representations. But any acoustic instrument or voice has produces tones that have the full spectrum.
C fundamental. 65Hz
The first partial. C an octave above. 130Hz
The second partial. G a fifth above. 195Hz
The third partial. A fourth above (third octave). 260Hz
The E a third above. 325Hz
Same C at 65Hz
The G a 5th above
The D a fifth above
The A a fifth above
The E a 5th above
