各音頻率的計算
小字1組的A音（簡譜的6=啦）是440Hz，國際標(biāo)準(zhǔn)。
把A4=440 乘以1.0594631 就是A#4=466.164,
再把A#4 X 1.0594631=493.883=B4.
往下440 除以1.0594631就得到G#4
這樣就可以計算出88個音的各自頻率.
任意相臨兩音的比值永遠(yuǎn)是1.0594631, 為什么?
它是2的開12次方, 這就是十二平均律!
Tunelab 軟件中把88鍵鋼琴最左邊的音叫A0, 最低的C叫C1, 以后順序?yàn)镃#1, D1, D#1,.......中央C叫C4.
調(diào)律的標(biāo)準(zhǔn)音是小字1組的A音,叫A4=440赫茲。
