**harmonics**of wave-lengths X, 2X, 3A, &c., where X=2AB and the conditions as to the values of y can be shown to require that the**harmonics**shall all have nodes, coinciding with the nodes of the fundamental curve.If then we resolve Ahbkc into

**harmonics**by Fourier's theorem, we may follow the motion of the separate**harmonics**, and their superposition will give the form of the string at any instant.Further, the same

**harmonics**may be easily obtained by touching the string at the first node of the harmonic required, and bowing at the first loop, and the presence of the nodes and loops may be verified by putting light paper riders of shape A on the string at the nodes and loops.Since the quality of the note sounded depends on the mixture of

**harmonics**, the quality therefore is to some extent dependent on the point of excitation.Thus, suppose a fundamental 256 has present with it overtone

**harmonics**512, 768, 1024, 1280, &c., and that we sound with it the major seventh with fundamental 480, and having**harmonics**960, 1440, &c. The two sets may be arranged thus c 256 512 768 1024 1280 h 480 960 1440, and we see that the fundamental of the second will beat 32 times per second with the first overtone of the first, giving dissonance.AdvertisementThe third volume includes, however, some theological treatises, and the first part of it is occupied with editions of treatises on

**harmonics**and other works of Greek geometers, some of them first editions from the MSS., and in general with Latin versions and notes (Ptolemy, Porphyrius, Briennius, Archimedes, Eutocius, Aristarchus and Pappus).For the mathematical investigation see Spherical

**harmonics**and dialectic, and that it was not until he had arranged for the carrying out of this programme that he devoted himself to the special functions of professor of philosophy.He showed, both by analysis and by synthesis, that quality depends on the order, number and intensity of the overtones or

**harmonics**that may, and usually do, enter into the structure of a musical tone.AdvertisementThe long vault has a certain keynote of its own, which, when firmly struck, excites

**harmonics**, including tones of incredible depth and sweetness.To how many sad hearts did he come like an angel, with the rich tones of his voice waking

**harmonics**.The current state of the art makes use of spherical

**harmonics**.Envelope amplitude modulation occurs in cochlear filtered speech because of unresolved

**harmonics**.The SAI pulses associated with the higher

**harmonics**are relatively narrow with respect to the changes in period during the pitch glide.However they could vibrate at much lower

**harmonics**, which could feasibly give rise to a low frequency hum.The album begins with a loop of guitar

**harmonics**, into which a drum kicks in, then the vocal.This was at the fundamental frequency and/or low-order

**harmonics**, not the high frequencies of noise.The last movement begins with overblown

**harmonics**using piccolos and bass & contra bass flutes.A brief climax slowly brings the music to a calm, rapt end, with the solo violin musing in glistening

**harmonics**.Love has shown that the great features of the relief of the lithosphere may be expressed by spherical

**harmonics**of the first, second and third degrees, and their formation related to gravitational action in a sphere of unequal density.'He further treated in a masterly manner of echoes and the mixture of sounds, and explained the phenomenon of grave

**harmonics**as due to the occurrence of beats so rapid as to generate a musical note.The expressions designated by Dr Whewell, Laplace's coefficients (see Spherical

**Harmonics**) were definitely introduced in the memoir of 1785 on attractions above referred to.It is known (see Spherical

**Harmonics**) that The maxima of C occur when d Ji(z) _Ji'(z) J1(z) =o; z) z z2 or by (17 when J2(z) =0.Using the term " note " for the sound produced by a periodic disturbance, there is no doubt that a well-trained ear can resolve a note into pure tones of frequencies equal to those of the fundamental and its

**harmonics**.Robert Smith (

**Harmonics**, 2nd ed., 1 759, p. 95) states that Sauveur " inferred that octaves and other simple concords, whose vibrations coincide very often, are agreeable and pleasant because their beats are too quick to be distinguished, be the pitch of the sounds ever so low; and on the contrary, that the more complex consonances whose vibrations coincide seldom are disagreeable because we can distinguish their slow beats; which displease the ear, says he, by reason of the inequality of the sound.Harrison did not, for example, recast the Great mixture as a

**harmonics**.Not only may the fundamental and its

**harmonics**be obtained separately, but they are also to be heard simultaneously, particularly the earlier ones, which are usually more prominent than those higher in the series.
