I previously hoped that the more multistyles, the better.
I tried more chord changes today, and found it was very good, the accompaniment was more stable, and it was more suitable for singing. So although it is just a pattern, the chord changes more, which will effectively improve the feeling of accompaniment repetition.
But I sang this song.
If you are doing rap, there may be fewer chords, and at most 1-4 chords may be used in the whole song. Because I found that many good songs have very few chords. Maybe they use a lot of substitutions?
