As a beginner you will probably quickly learn that the only way you are going to
improve your guitar playing is if you have a dedicated focused practice time. During this practice time it's a good idea to have exercises and drills that you work on to improve certain techniques like speed, picking, accuracy, finger position, and chords. These beginner guitar drills can be learned quickly and used during your next practice.
Chord change drill.
One common problem many beginner guitar players have is the delay or pause that is there between switching chords as their fingers try to get proper placement for the next chord. You are going to make random patterns of chords that should be different each time your practice. Then for the drill you will strum each chord once and do your best to change to the next chord as fast as possible. This type of exercise should be continually done every practice until you are comfortable as almost instantly switching chords.
Fretboard memorization drill.
The fretboard needs to be memorized. This means that you could name the note of any fret on the entire fretboard. If you practice tablature at all as you do learn a new song or riff, name the note in your head or out loud that you are playing. This will get you to quickly memorize the fretboard.
Picking drill.
A picking drill will increase the speed of your left and right hands so that you can pick notes faster and with more accuracy. There are two ways of doing this picking drill.
One is where you form chords with your left hand and pick them string by string with the right hand. You can go up and down the chord one string after another, but you can also skip strings and make your own patterns.
Another version of this involves scales. Learn a guitar scale and pick and play it at the same time. As a beginner guitar player having drills to do is very important. Learn some new practice material that will help you get better.
