It says he's working on something called mechanical harmonics ..." She looked over her shoulder again.
These sinusoids are called harmonics, overtones, or generally, partials.
Together, they make a set of functions called spherical harmonics.
These are called harmonics and have frequencies that are 2*f, 3*f, 4*f, 5*f..
These multiples are called harmonics of the fundamental frequency, and the process is termed harmonic analysis.
In addition to the basic pitch, called the fundamental, each note contains a series of frequencies called overtones or harmonics.
