As we see from Equation (6.8), the frequencies of all the harmonics of a taut
string are exact multiples of the fundamental frequency and form a harmonic series.
For most vibrating systems this is not the case. These will also vibrate at a series of
higher frequencies in addition to the fundamental frequency. These higher frequencies
are called overtones. However, in general, the frequencies of these overtones
will not be an exact multiple of the fundamental: they are not harmonic. A bell,
for example, will have overtones whose frequencies are not exact multiples of
the fundamental. When the bell is struck, the overtone frequencies will be heard
in addition to the fundamental. The skill of the bell maker is to ensure that the
combination of the fundamental and the overtones produces a sound that is not
discordant to the ear. (Of course, the term overtone can also be applied to a taut
string but in this case the overtones are harmonic.)
