I went to church as a child, and so I often had to sing in the choir, so I have had a good impression of music since childhood. And now, as an adult mother, I have to explain to my child that Chords are the basis of almost all Western music, and the most common function of the guitar is as an accompaniment instrument. But sooner or later, curiosity or necessity leads us to try to understand chords a little better. How do chords add up? How did they get these strange names? Why do some chords sound "good" and some sound "bad"? That's why my child and I are learning country guitar books.
