The musical interval between the second and third harmonics of a musical sound is a fifth. For the key of C:

    The musical interval between the third and fourth harmonics is a perfect fourth, in the diatonic scale, with a frequency ratio of 3:4, and the interval between the fourth and fifth harmonics is a major third which has a frequency ratio of 5:4. The next two harmonics, the fifth and sixth, span a musical interval of a minor third. For the key in the mud""
