The notation of notation 6 is the main key, and the mode scale is 6 7 1 2 3 5 6.
The upper corner is clear, just above Gong Yu.
There are 7 and 1 in the scale. Why is it determined that 7 is a positive tone or an angular tone, and 1 is an oblique tone? Personal analysis has four foundations:
(1) Seven notes * * * appear 8 times, 1 note * * * appears 5 times, and 7 is greater than 1 appears 3 times.
(2) Seven notes have one beat, while the longest note of 1 has only half a beat.
(3) There is no 1 tone in the first paragraph of the song, but it is a six-tone type with five tones. The second paragraph has 1 notes, but it is not as important as the 7-corner note.
(4) As a positive note, 7 appears on the important fulcrum of the melody. For example, the second bar is 6 7 3, and the seven notes of the penultimate bar are 3 7.
L 6-, this 7-note not only occupies the-beat value, but also plays an important role before the period tonic. You see 1 key is not in the important position of twisting. It plays a decorative role in the melody in the form of sound transmission or consonant.
To sum up, 7 tones are more effective than 1 tones, so 7 tones are positive angles, while 1 tones are off angles. So Selling Tangyuan is a six-tone folk song.
