thanks for your replies! I will work hard to learn chords.
However, I may not go to read. Because books are basically translated, I don’t understand. The most important thing is that I have been sleeping since I was young.
My main source of music theory knowledge comes from video and direct software operation.
With your help, I have a more in-depth understanding of BIAB. The more I use it, the more I like it. Not only can this software help to make music, but I think it is also a very good teaching software. It is difficult for me to understand some chords in a short period of time. I can only rely on memorization or familiarity with the operation. However, I believe that with the accumulation of time, I will change from mere memory to flexible use, and I will gradually get better. thank you all ^0^
