Python“制作”midi音乐“两只老虎”

从网上找了很多谱子，可惜没有音乐细胞看不太懂，根据自己的理解改了好几遍，还是听不出来“两只老虎”的感觉，于是在标题上加了双引号。这样的话就只能了解本文思路了，算是抛砖引玉吧，重点是Python标准库winsound的Beep()函数可以发出37到32767赫兹之间频率的声音，其第二个参数为发声时长。

from winsound import Beep

from random import randint

#列表中偶数位置是频率，奇数位置是时长

freqs = ['0FB', '08', '0F9', '08', '0FC', '08', '066', '08', '0FC', '08', '0C7', '08', '0FB', '08', '0F9', '08',

         '0FB', '08', '0F9', '08', '0FC', '08', '066', '08', '0FC', '08', '0C7', '08', '0FB', '08', '0F9', '08',

         '0FC', '08', '0C7', '08', '0FC', '08', '0F3', '08', '0FD', '10', '0A4', '10',

         '0FC', '08', '0C7', '08', '0FC', '08', '0F3', '08', '0FD', '08', '04A', '08',

         '0FD', '04', '04A', '04', '0FD', '04', '095', '04', '0FD', '04', '04A', '04', '0FC', '04', '0F3', '04', '0FC', '08', '0C7', '08', '0FB', '08', '0F9', '08',

         '0FD', '04', '04A', '04', '0FD', '04', '095', '04', '0FD', '08', '4A',  '04', '0FC', '04', '0FC', '04', '0FC', '08', '0C7', '08', '0FB', '08', '0F9', '08',

         '0FC', '08', '066', '08', '0FA', '08', '093', '08', '0FB', '08', '0F9', '08', '0FC', '04', '66', '04', '0FA', '08', '093', '08', '0FB', '08', '0F9', '08',

         '0FF', '10', '0FF', '10']

for i in range(0, len(freqs), 2):

    freq, d = map(lambda x: int(x, 16), freqs[i:i+2])

    d = d * 30

    #以指定的时长播放特定频率的声音

    Beep(freq, d)
