/======================================

应网友要求，下面再详细写一下乐谱和数据的转换关系。

以李叔同大师的《送别》的前二小节来说明转换的方法。

这部分的歌词是："长 亭 外， 古 道 边，"；

这部分的乐谱是：| 5 35 1 － | 6 16 5 － |。

（注意：乐谱中的1是高音，上边是带点的；还有些音符，应该有下划线，在这里都无法标出。感兴趣的网友应该去查看正规的乐谱。）

那么，据此就可以写出《送别》前二小节的数据表：

//--------------------------------------/

//code unsigned char sszymmh[] = {

//5, 2, 2, 3, 2, 1, 5, 2, 1, 1, 3, 4,

//嗦,中音,2个半拍;　咪,中音,1个半拍;　嗦,中音,1个半拍;　哆,高音,4个半拍

//6, 2, 2, 1, 3, 1, 6, 2, 1, 5, 2, 4,

//啦,中音,2个半拍;　哆,高音,1个半拍;　啦,中音,1个半拍;　嗦,中音,4个半拍

//0, 0, 0};

//结束标记

/--------------------------------------

记住：三个数字一组，代表一个音符。

第一个数字是1234567之一，代表音符哆来咪发；

第二个数字是0123之一，代表低音、中音、高音、超高音；

第三个数字是半拍的个数，代表时间长度。

当三个数字都是0，就代表乐曲数据表的结尾。

用这个数据表，替换掉程序中《世上只有妈妈好》的数据表，本程序就可以播放《送别》的前两小节。
