•以前，我听过一个神犇用C++函数做的音乐，当时的心里就十分激动：哇，好厉害啊，好神啊。
•这次，我终于通过自己无助的盲目的摸索、研究，写出了这篇文章（此时我的内心是鸡冻的233）
下面是正文：
•其实啊，Windows API 就提供了一个这样奇妙的发音函数，它就是Beep函数。Beep可以通过控制主板扬声器的发声频率和节拍来演奏美妙的旋律，本文根据音乐简谱来演奏几首优美的歌曲，用以展现Beep的疯狂魅力。
首先我们来Beep的函数原型：
|
1
2
3
4
|
BOOL Beep( DWORD dwFreq; DWORD dwDuration;); |
参数说明：
•dwFreq 指定要发出的频率(HZ)
•dwDuration 指定发音的时长，以毫秒为单位。
Beep的实际应用
•比如说我要发do这个音，do应该是523hz，且如果要发一拍的话，就相当于400毫秒。
•那这个函数就成了这样：Beep(523,400);
•但是，如果我们要连续的发出多个音的话，比如说像这样：
|
1
2
3
|
Beep(523,400);//do Beep(578,400);//re Beep(659,400);//mi |
•那岂不是太麻烦了，所以，我建议大家用define函数宏定义一下这些音，比如说这样：#define re 578和#define mi 659，这样，上面的三行语句就简化了成这样：
|
1
2
3
|
Beep(do,400);Beep(re,400);Beep(mi,400); |
最终，给亲们送上一份表（借别人的 划去)
其中，q前缀为低音，1后缀为高音，s前缀为半音阶

最后，（嘿，同志们，别跑，后面还有彩蛋呢！）
好吧，是一首用Beep函数演奏的天空之城
