曲譜存貯格式 unsigned char code MusicName{音高，音長，音高，音長...., 0,0}; 末尾:0,0 表示結(jié)束(Important)
音高由三位數(shù)字組成： 個位是表示 1~7 這七個音符 十位是表示音符所在的音區(qū):1-低音，2-中音，3-高音; 百位表示這個音符是否要升半音: 0-不升，1-升半音。 音長最多由三位數(shù)字組成： 個位表示音符的時值，其對應(yīng)關(guān)系是： |數(shù)值(n): |0 |1 |2 |3 | 4 | 5 | 6 |幾分音符: |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-連音，2-頓音 百位是符點位: 0-無符點，1-有符點
調(diào)用演奏子程序的格式
Play(樂曲名,調(diào)號,升降八度,演奏速度);
|樂曲名 : 要播放的樂曲指針,結(jié)尾以(0,0)結(jié)束;
|調(diào)號(0-11) : 是指樂曲升多少個半音演奏;
|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;

以下為曲譜編碼文件，自己可以根據(jù)規(guī)則，對照簡譜編寫曲譜編碼表，我已經(jīng)做好了一個應(yīng)用程序，只需將簡譜輸入進去，就可以直接輸出曲譜編碼表，省去人工編碼的痛苦。此軟件作為共享軟件發(fā)布，有需要的請留言，此東東絕對是搞電子設(shè)計在校大學(xué)生泡MM的巨佳手段，呵呵。
