- 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,调号,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;
- |调号(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;
