《铃儿响叮当》是一首脍炙人口的经典圣诞歌曲，今晚平安夜我来用python奏起来——
用最原始的winsound库函数Beep()来演奏，用法如下：
私信小编01即可获取大量Python学习资源
>>> import winsound>>> help(winsound.Beep)Help on built-in function Beep in module winsound:Beep(frequency, duration)A wrapper around the Windows Beep API.frequencyFrequency of the sound in hertz.Must be in the range 37 through 32,767.durationHow long the sound should play, in milliseconds.
先找来do,re,mi等音符的频率表：
'''休止符及do re mi等对应的频率数'''
Tone = [[0,0,0,0,0,0],[523,262,1046,554,277,1109],[578,294,1175,622,311,1245],[659,330,1318,659,330,1318],[698,349,1493,740,370,1556],[784,392,1568,831,415,1661],[880,440,1760,932,466,1865],[988,494,1976,988,494,1976]]
然后找一份最简版的《铃儿响叮当》简谱：
照此编制乐谱，自定义一个规则，每个音符为一个元组：（音符，音长，音阶）
简谱的每个音符用一个三元素元组表示，其中：
第一个元素 1~7 对应do re mi fa so la si 0=休止符
第二个元素 1拍=1；半拍=0.5 四分之一拍=0.25 以此类推
第三个元素一般就为0，低音=1 高音=2 对应的半阶音=3 4 5
这样定义方便乐谱的编制，代码如下：
from winsound import Beep'''休止符及do re mi等对应的频率数'''Tone = [[0,0,0,0,0,0],[523,262,1046,554,277,1109],[578,294,1175,622,311,1245],[659,330,1318,659,330,1318],[698,349,1493,740,370,1556],[784,392,1568,831,415,1661],[880,440,1760,932,466,1865],[988,494,1976,988,494,1976]]'''乐谱编制'''t1 = '33333335123't2 = '444333322125't3 = t1t4 = '4444433355421''''对应的音长'''p1 = [1,1,2,1,1,2,1,1,1.5,0.5,4]p2 = [1,1,2,1,1,2,1,1,1,1,2,2]p3 = p1p4 = [1,1,1.5,0.5,1,1,1,1,1,1,1,1,4]t = list(map(int,t1 t2 t1 t4))p = p1 p2 p1 p4Tune = list(zip(t,p,[0]*len(t))) #配曲音符都为中音，音阶值全为0'''演奏乐谱'''Pai = 360#一拍的毫秒数，可以调节for t in Tune:Beep(Tone[t[0]][t[2]],int(t[1]*Pai))
按下运行键，动听的演奏开始了：
“叮叮当,叮叮当, 铃儿响叮当.
我们滑雪多快乐,我们坐在雪橇上...”
祝大家平安夜快乐，全家平安幸福！为方便初学者理解怎样把简谱转换成Tune列表，另附一首《两只老虎》：
