Here is some knowledge that I think you should know in order to improve your guitar playing. At first, I think you should learn the chords you use most often, such as C and G, and start practicing the songs you can play with those chords, but when you start to play # and b chords, I think it will be difficult to remember them. Also, when you play a solo, it is easier to remember if you know where to press to play the notes.
So, first of all, here is some advice on how to remember guitar chords and scales by associating them with their musical meaning. I’m not very good at memorizing, so this is a method I learned to make it a little easier for me. I hope this will be of some help to those who are learning the guitar.
