Home As it is known, any sound in the nature consists of fluctuations of the elementary components - pure sinusoidal tones. The timbre is formed from некоторго numbers of such tones built on, so-called harmonious обертоновому to a number. Besides. At a sound spectrum there can be various harmonious additional sounds, noise effects (for example, a bow friction about a string), разностные tone (arising third tone from fluctuation of two) and even унтертоновые formations (обертонный a number mirror отражeнный). And all this complex of elements depends on the tool form (so-called форманты) in which they exist. The tool form - the original filter where one areas of a timbre are in full or in part cut off, and others are audible more boldly. Thus, along with character of occurrence of a sound (attack) depends on the tool form individuality of a timbre in the sounding tool. Components all these named, creating and defining a timbre if them to consider in some определeнные time moments, will have a various overall picture. In the sum they also represent dynamic transitive sound processes in a timbre which in some set limits under natural conditions vary with frequency about 20 Hertz (20 times a second). The sounds answering to such minimum conditions, we also define as "live".
