Statistically, the fundamental tone and harmonic amplitude of the No.
We rarely hear a pure fundamental tone either in music or in nature.
Because Stockhausen's serial conception of durations is no longer based on the multiplication of a smallest rhythmic value, but rather starts from the equal division of a metrical "fundamental phase" [22]--which is undefined in its temporal dimension to begin with but is thought of as equivalent to the fundamental tone, he developed in a second stage a "tempered chromatic scale of durations" (Stockhausen 1959, 21) with reference to the fundamental phases--in analogy to the twelve "fundamental tones" of the octave.
At the output, the amplified fundamental tones are present in addition to several harmonic frequencies.

58), and further - and with equal originality - that "the structure of Rameau's genealogy of sound, from the fundamental tones of the corps sonore to the complex configurations of music, is reproduced in Condillac's synchronic view of knowledge" (p.
In the first of three movements, the oscillations contain both fundamental tones and harmonics, almost like the sounds from a musical instrument.
It is apparent from the graph that the third-order intermodulation products (2[f.sub.1]-[f.sub.2]) and (2[f.sub.2]-[f.sub.1]) are the most significant contributor to distortion in that they are very near the fundamental tones and are not readily filtered out as is the case of the third-order intermodulation products (2[f.sub.1]+[f.sub.2] and 2[f.sub.2]+[f.sub,1]) and the second-order intermodulation products ([f.sub.1]-[f.sub.2], 2[f.sub.1], [f.sub.1]+[f.sub.2] and 2[f.sub.2]).
