Music majors, except those who study percussion, basically use staff and notation, which belongs to melody music. Knowing music can basically sing the rhythm and pitch of music, that is, knowing music.

However, in modern guqin, when using staff or notation, in most cases, it has to be used in conjunction with the unique "subtraction notation" of guqin. Subtraction notation is a fingering notation, which only expresses fingering (how to play a certain sound) and melody (pitch, rhythm, etc.). ) I can't see it intuitively, so it's not convenient to sing. Subtraction spectrum looks like a gobbledygook on the surface, but it is actually very simple, a bit like a spelling bee. There is a wealth of information on the Internet, and anyone who is blind in guqin music can learn to recognize it by himself.

Most students majoring in music don't know this is normal because they haven't been exposed to subtraction notation, but they can recognize the melody part (staff or notation) in modern guqin notation, because most modern musical instruments use staff and notation.
