Description

Large resonance and large tension bamboo flute

Technical Field

The invention relates to a large-resonance and large-tension bamboo flute.

Background

The sound generated by the vibration of the object parts is called overtone, the volume of the overtone is small, the sound is not easy to hear for human ears, but the sound does not exist, and the sum of the sound and the overtone is called composite sound. Each tone is a composite tone composed of a fundamental tone and an overtone. The sounding body has various vibration modes with different frequencies, and the corresponding frequencies of the various vibration modes have corresponding sounds. The basic sound and each overtone are listed on the music score to form a sound list, namely, each sound in the partial list has the name: namely a first partial (fundamental), a second partial (first overtone), a third partial (second overtone) … … and so on.

Then the pitches of the notes are naturally known first to be listed in the score. We start with the frequency of each tone: we have previously derived from an analysis of the vibration of the string that for a uniform string of length l, the nth mode of vibration (i.e. corresponding to the nth partials) has a frequency na/2l, where a is the velocity of the wave on the string, and is related to the properties of the string itself. That is, the frequency of the nth partials is n times the fundamental tone.

If the large word group C is used as the fundamental tone: the first overtone (second partial), which is a tone at 2 times the fundamental frequency, is modeled in the manner described above, and is found: just eight degrees higher than the fundamental tone. When C is used as the fundamental tone, the first harmonic is C of the small word group. The second overtone (third overtone), if processed, is heard at five degrees above the first overtone, which is here g at five degrees above c. The third harmonic (fourth harmonic) is heard one sound and is further pitched by pure octaves than the first harmonic. This is of course because the third harmonic frequency is 4 times the fundamental, naturally 2 times the first harmonic, and of course is an octave higher, as is the relationship between the first harmonic and the fundamental. Here c1 for a group of small words. The fourth harmonic (fifth harmonic) has a frequency ratio of 5:4 to the third harmonic, which is three degrees greater than the third harmonic, here e 1. The fifth harmonic (sixth harmonic) is higher than the fourth harmonic by three degrees, i.e., higher than the third harmonic by five degrees. Again, an identical interval appears. Since the frequency ratio of the second harmonic to the first harmonic is 3:2, and the frequency ratio of the fifth harmonic to the third harmonic is 6:4 to 3:2, the ratio is higher than the third harmonic by five degrees — g 1. The frequency ratio of the sixth overtone (seventh partials) to the fifth overtone (sixth partials) is 7:6, which does not correspond well to the frequency ratio, and since it is relatively close to 6:5 (1.1666666 … … and 1.2 … …), it is generally considered to be three degrees lower (slightly lower in reality) than the fifth overtone, and is noted as

b1. The seventh harmonic (eighth harmonic) is 8 times the fundamental frequency, i have said that i have no more than said, and it is of course octave of higher purity than the third harmonic, i.e. c 2. The frequency ratio of the eighth overtone (ninth partion) to the seventh overtone (eighth partion) is 9: 8. The frequency ratio of the ninth overtone (tenth overtone) to the eighth overtone (ninth overtone) is 10: 9.

The two frequency ratios are actually very close (1.125 and 1.111111111 … …). In the pure law, which is a law based on partials, the relationship between the two groups of tones is considered as whole tone, the former called major whole tone, and the latter called minor whole tone. However, it is not difficult to set their bits in the phonetic column: the frequency ratio of the eighth harmonic (ninth harmonic) to the fifth harmonic (sixth harmonic) is 9:6 to 3:2, the frequency ratio of the ninth harmonic (tenth harmonic) to the seventh harmonic (eighth harmonic) is 10:8 to 5:4, the former is also pure fifth, and the latter is in the same relationship with the fourth harmonic and the third harmonic, i.e. in greater third. So one is pure five degrees d2 above g1 and one is the greater three degrees e2 above c 2.

The latter tones get finer and finer, and many are approximated. Before the sixteenth partials (fifteenth partials, three groups of small words c3), namely the eleventh, thirteenth and fourteenth partials (twelve, fourteen and fifteen partials) have the relation of appearance and previous repetition, each bit can be analyzed by itself. In addition, the fifteenth and sixteenth partials (fourteenth and fifteenth overtones) are semitone relationships in pure law.

The overtones are the concept that we have not well understood — timbre. The fundamental frequency component is not surprising because the first coefficient is the most natural thing, the largest coefficient is the most natural thing, so the meaning of overtones is here-the tone, resonance and tension of the sounding body are determined by the amount of the overtone component when the sounding body vibrates. The large-resonance high-tension bamboo flute does not exist in the market; the applicant provides further improvement on the basis and designs a large-resonance high-tension bamboo flute so as to meet the requirements of the existing market.
