Guitar fun, what skills do you need to write your own songs? I practice folk songs, chord problems? ?

You are the most potential comrade I have answered, because you know troubles and emotions. Isn't it easy to change songs?

Turning a song is to turn emotion into the collocation of each note (D and M collocation will make people feel rhythmic). As long as there are feelings, it is only a matter of time. It will be better to express your feelings by studying how to match them, so I say you have potential because you have passed the most difficult stage!

The real name of a chord is "harmony". What is harmony? Chords are annoying and hard to remember, right?

Chords are just a combination of keys pressed by each finger and a name! There is only one thing to remember: C chord! This is the basis of universal chords. The charm of chords is just the different effects of note collocation mentioned above, as simple as that!

Is it okay to write songs with chords?

I'm sure: no! Although the chords of everything are in C, not every song is in C! You can give it a name (for example, c' or h) with the notes you have learned. That's why there are so many chords, because too many people invented them!
