一般说来，单片机配合外接的蜂鸣器可以发出基本的单音频率。由于蜂鸣器发出的声音不包含相应幅度的谐波频率，因此采用这种方法不能演奏出多种音色的声音。使用单片机配合蜂鸣器来发音，只需弄清楚两个概念即可，也就是“音调”和“节拍”。其中，音调表示一个音符唱多高的频率；节拍表示一个音符唱多长的时间。下面分别介绍音调和节拍的相关知识，以及如何使用单片机来实现音调和节拍。
节拍表示一个音符唱多长的时间，其同样是音乐学中的名词。在一张完整乐谱的开头，都有如1=C 、1=G …… 等的标识。例如1=G 的节拍示意图。
这里的、用来表示节拍，而1=C、1=G表示一个乐谱的曲调，简单地说就是跟音调有关系。
前面介绍了基本音符的音调和节拍，并详细讲解了如何在单片机系统中来实现一个基本的音符。在单片机上实现音乐播放，一般只需逐个播放音符即可。用单片机播发音乐的方法如下：
（1）初始化单片机定时器；
（2）将乐谱中的每个音符的音调及节拍变换成相应的音调参数和节拍参数；
（3）将乐谱中音符的参数做成数据表格，存放在存储器中；
（4）通过程序取出一个音符的相关参数，驱动蜂鸣器播放该音符；
（5）该音符唱完后，接着取出下一个音符的相关参数……，如此直到播放完毕最后一个音符，根据需要也可循环不停地播放整个乐曲。
