They are defined by having frequencies three and five times that of the
fundamental - that is what the terms "third harmonic" and "fifth
harmonic" mean. As I said, _no_ eqally tempered intervals (apart from
octaves) actually coincide with harmonics. Equal temperament involves
putting everything slightly out of tune.

It is some sort of coincidence, I guess, that the third harmonic is
(one octave and) a fifth above the fundamental, and the fifth is (two
octaves and) a third above the fundamental - please don't get confused
by the two different uses of '''third and fifth'. Life can never be
that simple! :-)>

Hope that helps.
