我想問笛譜的123怎樣變成CDEFG吹

C . D . EF . G . A . BC . D . E F . G . A . BC..............

1 . 2 . 34 . 5 . 6 . 71 . 2 . 3 4 . 5 . 6 . 71 ...............................


C = 1 , D = 2 , E = 3 , F = 4 , G = 5 , A = 6 , B = 7


照數就得

音名(牧童笛吹的);C D E F G A B C' D' E'.........
║

唱名(用口唱的); 1 2 3 4 5 6 7 8 9 10 ........
║

唱名(用口唱的); d r m f s l t d' r' m' .........

全部都係相對的!!!

1 2 3 4 5 6 7
D R M F S L T
C D E F G A B
