Harmonic Series Revisited

Here is an example of the harmonic series generated by the low C that vibrates at 131 Hz:

Harmonic Number Frequency in Hz Note Interval from Fundamental Interval from Previous Harmonic
1 (fundamental) 131 C3 unison -
2 262 C4 octave octave
3 393 G4 octave plus a fifth perfect fifth
4 524 C5 2 octaves perfect fourth
5 655 E5 2 octaves plus a major third major third
6 786 G5 2 octaves plus a fifth minor third
7 917 almost B-flat5 2 octaves plus a small minor seventh small minor third
