An overtone is a natural resonance of a system. Systems described by overtones are often sound systems, for example, blown pipes or plucked strings. If such a system is excited, a number of tones may be produced along with the fundamental tone. In simple cases, such as for most musical instruments, the frequencies of these tones are the same as the harmonics. An example for an exception is a circular drum, whose first overtone is 2.4 times its fundamental resonance frequency. The human vocal tract is able to produce a highly variable structure of overtones, called formants, which define different vowels.
