相信您在作蜂鸣器发声实验时肯定为复杂的频率与音调之间的转换而伤脑筋，这里向大家介绍一款工具可以大大简化转换操作，只需要输入简谱就能自动生成音乐播放程序代码。
以下此程序的主界面：
程序范例可以点主界面上的“关于”按钮后就能找到，但是代码也不全，需要加入对音乐程序的调用代码，其它范例里也写的很清楚了，只需要调用Play函数就行了，其调用格式如下：
Play(乐曲名,调 ,升降八度,演奏速度);
经过实践，此函数的的后三个参数分别设为0,2和350时演奏出的音乐比较符合“原味”，下面给出本站的入门型51实验板结合此工具作的音乐程序：

曲谱存贮格式 unsigned char code MusicName{音高，音长，音高，音长…., 0,0}; 末尾:0,0 表示结束(Important)
音高由三位数字组成：
个位是表示 1~7 这七个音符
十位是表示音符所在的音区:1-低音，2-中音，3-高音;
百位表示这个音符是否要升半音: 0-不升，1-升半音。
音长最多由三位数字组成：
个位表示音符的时值，其对应关系是：
|数值(n): |0 |1 |2 |3 | 4 | 5 | 6
|几分音符: |1 |2 |4 |8 |16 |32 |64 音符=2^n
十位表示音符的演奏效果(0-2): 0-普通，1-连音，2-顿音
百位是符点位: 0-无符点，1-有符点
调用演奏子程序的格式
Play(乐曲名,调 ,升降八度,演奏速度);
|乐曲名 : 要播放的乐曲指针,结尾以(0,0)结束;
|调 (0-11) : 是指乐曲升多少个半音演奏;
|升降八度(1-3) : 1:降八度, 2:不升不降, 3:升八度;
|演奏速度(1-12000): 值越大速度越快;

再例如：关于“世上只有妈妈好”的单片机音乐演奏程序
单片机演奏一个音符，是通过引脚，周期性的输出一个特定频率的方波。
这就需要单片机，在半个周期内输出低电平、另外半个周期输出高电平，周而复始。
半个周期的时间是多长呢周知，周期为频率的倒数，可以通过音符的频率计算出半周期。
演奏时，要根据音符频率的不同，把对应的、半个周期的定时时间初始值，送入定时器，再由定时器按时输出高低电平。
下面是个 上广泛流传的单片机音乐演奏程序，它可以循环的播放“世上只有妈妈好”这首乐曲。很多人都关心如何修改这个乐曲的内容，但是不知如何入手。
做而论道对这个程序，给出说明，希望对大家有所帮助，以后大家自己就能够编写进去新的乐曲。
在这个程序中，有两个数据表，其中存放了事先算好的、各种音符频率所对应的、半周期的定时时间初始值。
有了这些数据，单片机就可以演奏从低音、中音、高音和超高音，四个八度共28个音符。
演奏乐曲时，就根据音符的不同数值，从半周期数据表中找到定时时间初始值，送入定时器即可控制发音的音调。
比如把表中的0xF2和0x42送到定时器，定时器按照这个初始值来产生中断，输出的方波，人们听起来，这就是低音1。
乐曲的数据，也要写个数据表，程序中以 code unsigned char sszymmh[] 命名。
这个表中每三个数字，说明了一个音符，它们分别代表：
第一个数字是音符的数值1234567之一，代表多来咪发…；
第二个数字是0123之一，代表低音、中音、高音、超高音；
第三个数字是时间长度，以半拍为单位。
乐曲数据表的结尾是三个0。
程序如下：
#include sbit speaker = P1^7;
unsigned char timer0h, timer0l, time;
//————————————–
//单片机晶振采用11.0592MHz
// 频率-半周期数据表 高八位 本软件共保存了四个八度的28个频率数据

//======================================
应 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 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。
