First of all, I'm not an expert, I just want to communicate with you. I have practiced the city of the sky myself, and I didn't deliberately remember the music score, but I can play it out with the guitar, because my fingers have muscle memory, and I haven't studied music theory. I don't know what the sound is, but I only know that it is pressed on the string of this product.

You thought solo was good, so you practiced it. You can hear the feelings of this piece of music, so you practice it, rearrange it, and pop up your feelings and understanding.
