4、色标注，最高频率用蓝色标注。（上面的频率表是google上找来的，转帖，致谢！）各音频率的计算小字1组的A音（简谱的6=啦）是440Hz，国际标准。把A4=440乘以1.0594631就是A#4=466.164,再把A#4X1.0594631=493.883=B4.往下440除以1.0594631就得到G#4这样就可以计算出88个音的各自频率.任意相临两音的比值永远是1.0594631,为什么?它是2的开12次方,这就是十二平均律!Tunelab软件中把88键钢琴最左边的音叫A0,最低的C叫C1,以后顺序为C#1,D1,D#1

5、,.......中央C叫C4.调律的标准音是小字1组的A音,叫A4=440赫兹。
