十二平均律作为一种可以方便转调的律制被广泛应用,它将音乐中一个八度(即二倍)音程等比分成十二个音级,每两个相邻音级(即两个相邻半音)均相差~(12)2~(1/2)≈1.059463倍关系,并且每个音级都对应有各自的音名,从大字二组到小字五组。当标准音高确定为a~1=440Hz后,每个十二平均律的音名也就有了各自的固定音高频率。有资料表明,人的听辨声音的能力一般在20Hz~20000Hz频率范围内,人的发声一般在65Hz~1100Hz频率范围
The Twelve Average Law is widely used as a system of rules that can be easily redirected. It divides one octave (ie double) interval in music into twelve levels, and every two adjacent levels (ie, two Adjacent semitones) are all ~ (12) 2 ~ (1/2) ≈1.059463 times the relationship, and each sound level corresponds to their respective phonetic names, from two characters to five small characters. When the standard pitch is determined as a ~ 1 = 440Hz, the pitch of each twelve-level average law also has its own fixed pitch frequency. Data show that people’s ability to listen to the sound of the general 20Hz ~ 20000Hz frequency range, the human voice is generally in the 65Hz ~ 1100Hz frequency range
