We should, in theory, first figure out what natural and natural overtones are and how they are generated. We are natural harmonic series not only should be remembered, and should be able to move, if you can hold ten set a tone of natural harmonic series, so for future practice will bring great convenience. The natural harmonics We strain a string on a stringed instrument to make it to a certain degree of tightness, then rub it with a bow or a hand, and it will produce a certain pitch. The lowest note emitted when the string is vibrating without a hand (i.e., empty string) is called a base note. The same is true for wind instruments. The lowest note of the full-length vibration of its air column when not pressed refers to the · kwai tone. IN the stringed instruments, the change of position IN the finger position allows the natural overtones The fundamental changes. In brass instruments, it is the method of increasing the length of the pipe to change the shittone. The pipeline can be increased six times, together with the original pipe length of seven. The base notes of brass instruments are difficult to play and the tone is poor, so the keyin of individual brass instruments can be applied without it. The natural harmonics But, regardless of the strings of strings or the air columns of wind instruments, we can try to make them vibrate at the same time, except for the base notes. On a stringed musical instrument, for example, with a hand of light erosion empty string a first-class points, to rub or plucked it, on the wind inst
