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
