今天我们再接着上期的话题,继续聊聊音乐中的奇妙数学。上期说到的黄金分割很有意思。其实,音乐作品中还有不少黄金数列——菲波拉契数列,比如“乐器之王”钢琴的键盘排列就与斐波那契数列有关。钢琴键盘上的C键到下一个C键就是音乐中的一个八度音程,这其中共包括13个琴键,有8个白键和5个黑键。这5个黑键分成两组,一组有两个黑键,另一组则是3个黑键,2、3、5、8、13这几个数字恰好就是著名的斐波那契数列中的前几个数。
Today, we then continue the topic of the previous period, continue to talk about the wonderful mathematics in music. The golden section of the last issue is very interesting. In fact, there are many gold works in the music sequence - the Fibonacci sequence, such as “the king of musical instruments ” piano keyboard layout and the Fibonacci sequence related. The C key on the piano keyboard to the next C key is an octave in the music, which includes a total of 13 keys, eight white keys and five black keys. The five black keys are divided into two groups, one with two black keys and the other with 3 black keys. The numbers 2,3,5,8,13 happen to be in the famous Fibonacci sequence The first few numbers.
