In order to achieve musical harmony, in the previous piece, two tracks and two instruments, were with different melodies, but with the same chord progression. Different musical instruments have different styles and melody characteristics. But the chords are basically matched. The echo may be early or late. But there will be no parallel chords that are conflicting with each other.
Tried different chord progression today, even a slightly different in scales. See if they can harmonize.
The purpose is for freedom, for novelty, for the surprise in the melody.
It's as if two are in love, but one is Romeo and the other is Juliet, with different origins, backgrounds and families.
At least, distinguish us from AI (representing the existing principles and rules of music)
Give it a try.
