Description
本发明属于现代音乐工业领域,具体涉及一种面向毕达哥拉斯律的反对称律列产生方法。The invention belongs to the field of modern music industry, and particularly relates to a method for generating antisymmetric temperament oriented to Pythagorean temperament.
在音乐艺术领域,音律是音乐实践和音乐研究的主要内容之一,毕达哥拉斯律是一种音律的律制,在现代中国常常被称为五度相生律,在古代中国被称为三分损益律,它是分别由古希腊时期的毕达哥拉斯学派和中国先秦时期的音乐家各自独立提出的,已有二千多年的历史,在世界各地广为使用,存见的大多数乐器的都采用毕达哥拉斯律为定律的方法,毕达哥拉斯律为全人类的音乐事业的传承与发展做出了巨大贡献。In the field of music art, rhythm is one of the main contents of music practice and music research. Pythagorean rhythm is a rhythm system of rhythm. The law of three points of profit and loss, which was independently proposed by the Pythagoreans in ancient Greece and the musicians in the pre-Qin period in China, has a history of more than 2,000 years and is widely used all over the world. Most musical instruments use the method of Pythagorean law, which has made great contributions to the inheritance and development of the music industry of all mankind.
但是,现代世界已经进入了数字音乐时代,国际流行的毕达哥拉斯律仍然采用毕达哥拉斯学派提出的古老的生律方法,已经不适合于数字音乐的飞速发展。图1示出常用的毕达哥拉斯学派生律方法的音律结构图,它的基本规则是:人为给定起始律的频率,如通常以乐音体系的中央C的频率为261.63Hz,作为起始频率,按上行纯五度和下行纯五度两个方向链式生成音律。上行纯五度,就是当前音律的频率乘以
或
如果当前音律的频率乘以
不超过起始律频率的2倍,则下一律的频率为当前音律频率乘以
否则乘以
图1中的上一行(1)表示从中央C出发,按纯五度上行生律,通过乘以
或
得到下一律。下行纯五度,就是当前音律的频率乘以
或
如果当前音律的频率乘以
不超过起始律频率的2倍,则下一律的频率为当前音律频率乘以
否则乘以
图1中的下一行(2)表示从中央C出发,按纯五度下行生律,通过乘以
或
得到下一律。这个 方法虽然把生成的音律约束在了起始律频率的2倍以内,但是每计算一律都要选择乘法因子,同时,为了计算某一音律,必须先计算出它前面的各个音律,如要计算乐音b的频率,必须先分别计算出g、d、a、e等四个乐音的频率。
However, the modern world has entered the era of digital music, and the internationally popular Pythagorean rhythm still adopts the ancient method of biological rhythm proposed by the Pythagorean school, which is no longer suitable for the rapid development of digital music. Figure 1 shows the temperament structure diagram of the commonly used Pythagorean derived temperament method. Its basic rule is: the frequency of the initial temperament is artificially given, for example, the frequency of the central C of the musical tone system is usually 261.63Hz, as The starting frequency is used to generate the temperament in two directions: the upward perfect fifth and the downward perfect fifth. The upward perfect fifth is the frequency of the current temperament multiplied by or If the frequency of the current temperament is multiplied by If not more than 2 times the frequency of the initial temperament, the frequency of the next temperament is the frequency of the current temperament multiplied by otherwise multiply by The upper line (1) in Figure 1 indicates that starting from the center C, according to the law of perfect fifth ascending, by multiplying by or Get the next one. The descending perfect fifth is the frequency of the current temperament multiplied by or If the frequency of the current temperament is multiplied by If not more than 2 times the frequency of the initial temperament, the frequency of the next temperament is the frequency of the current temperament multiplied by otherwise multiply by The next line (2) in Figure 1 shows that starting from the center C, according to the descending law of perfect fifths, by multiplying by or Get the next one. Although this method constrains the generated temperament to be within 2 times of the frequency of the initial temperament, the multiplication factor must be selected for each calculation. For the frequency of the tone b, the frequencies of the four tones g, d, a, and e must be calculated separately.
因此,迫切需要一种能方便计算的音律计算公式和音律产生***,从而解决数字音乐时代毕达哥拉斯律的广泛应用问题。Therefore, there is an urgent need for a temperament calculation formula and a temperament generation system that can be easily calculated, so as to solve the problem of wide application of the Pythagorean temperament in the digital music era.

Described step 3) in, divide by three method unit 21 temperament calculation formula is: Wherein {-j×log 2 3} means to take the value of the fractional part of the value -j×log 2 3, use this formula to calculate the frequencies of N temperaments, and press the calculated frequencies of the N temperaments to the size of j, Arrange from big to small to get the sequence F', that is, F'=<f' N ,f' N-1 ,...,f' j+1 ,f' j ,...,f 1 '>.

In the step 4), the composition method of the sequence F, the sequence F' and the central onset law is Ω=<F'f 0 F>=<f' N , f' N-1 ,...,f' j ..., f 1 ',f 0 ,f 1 ,…,f i ,…,f M-1 ,f M >.
由于{-j×log

23},因此,可以把乘三法音律计算公式和除三法音律计算公式统一表示为:
其中Z表示整数。这样,当k=0时,就可得到中心起始律f
0,当k>0时,就可得到数列F,当k<0时,就可得到数列F'。
Since {-j×log 2 3}={(-j)×log 2 3}, the multiplication-by-three temperament calculation formula and the division-by-third temperament calculation formula can be unifiedly expressed as: where Z represents an integer. In this way, when k=0, the central starting law f 0 can be obtained, when k>0, the sequence F can be obtained, and when k<0, the sequence F' can be obtained.
因为对于任何下标i,都满足
乘积是常数2,因此数列F和数列F'是反对称关系,也即反对称律列Ω是反对称数列。
because for any subscript i, The product is a constant 2, so the sequence F and the sequence F' are antisymmetric, that is, the antisymmetric law sequence Ω is an antisymmetric sequence.

For the convenience of calculation, most Music software often uses twelve well-tempered, twelve well-tempered calculations are simple and easy to understand, and the calculation formula is: But from the perspective of music theory, the twelve equal temperament is a dissonant temperament system. In the long musical practice of human beings, the Pythagorean temperament is the most widely used temperament, but the commonly used physical temperament method of the Pythagorean temperament requires a certain degree of musical knowledge to understand, and its temperament calculation method is more than ten The two-average law is complex, so its scope of use is greatly reduced.
