说明：  下载别人的谢谢原作者2. 程序编译说明：用3*7数组定义21个音阶。读取已有的自编的乐谱文件，按文中内容奏乐，若文中有不合规定的字符，显示”press any key to exit”。用getmsckey()函数来得到频率数组坐标，用play()函数获取拍数及频率数组坐标。
(Thank you download other people's two original author. Compiler Note :* 7 3 array definition 21 chromatic. Readers have written the scores of documents, according to the text content of music, if the text were irregularities of the characters, shows that the "press any key to exit." With getmsckey () function to get the frequency array coordinates with play () function to obtain the number and frequency shoot array coordinates.)
