Guitar scales are one of the most effective practice exercises that you can do as a beginner acoustic guitar player. I know guitar scales can seem a bit boring, especially when you are playing them every day, but hang in there. Guitar scales build strength, speed and dexterity. They will familiarize you with the guitar and will make you a better musician in the long run.
Your best course of action is to learn the major scales first. I made this process as easy as possible for you by including videos below on how to play all of the major guitar scales.
Do not try and play these acoustic guitar scales all at once. Learn the first scale listed below until you can play it all on your own from memory without any mistakes, and then move on to the next. Go very slow at first and make sure you are playing each note correctly by producing a clean sound. While you play each note, either say the name of the note out loud or in your mind. This will help you remember how to play the notes of the guitar.
