How to find the mode urgency of chromatic scale? . .

The chromatic scale in basic music theory is mainly about the chromatic scale of major and minor modes.

The formula for a chromatic scale with a large elevation is #i #ii #Iv #v bvii. The formula of the chromatic scale is: bvii bvi #iv biii bii. Any chromatic scale that satisfies this formula is a major tonality.

For example, 1. Uplink1# I 2 # 234 # 45 # 56b71.

One, two, three, four, five, six, seven, one

Example 2 Downstream17b76b65 # 443b32b21

I. vii bvii vi bvi v # iv vi iii biii ii biii

The formula of small crescendo is: bii #iii #iv #vi #vii. The formula for the chromatic scale is: #vii #vi #iv #iii bii Any chromatic scale that meets this formula is a minor.

For example, 1. Uplink 6b771#12 # 234 # 45 # 56.

Downlink 6 # 55 # 443 # 22 #117b76

The ascending line and descending line of minor chromatic scale are symmetrical in reflection, which is easy to find.
