Now you have learnt the chords, but you may have found changing chord is challengingly hard. Yeah, it’s true, it is very hard to change the chords at beginning. You might have thought to give up, but don’t worry; we will guide you to change the chord easily and effectively.
1. Remember the shape
Your goal is to increase the muscle memory. Remember it was how hard to play a single chord previously, but now you can play them without any problem. It is due to the muscle memory. Now it’s time to increase that memory to little bit higher. You have to train your fingers to remember the basic shapes of the chords.
When you are playing a chord; do you put your index finger first, then middle and then ring? Honestly it is a bad habit. Your fingers must remember the whole shape. So next time, when you put your hand to the fret-board to play chord, avoid to put index finger first, then middle and then ring. Instead try to put all finger at chord positions at the time. 
2. Repeat the action over and over again
It is very simple exercise yet very effective. Put the fingers on fret-board and play a chord. And then lift off your fingers without changing the shape. After some time put back your fingers to the chord. You have to do this with every chord. If you do this honestly, your chord changing will be improved dramatically. 
3. Steve Stine’s method
Steve Stine is known as the world’s most sought-after guitar instructor. After years of struggling to understand how the guitar “really works,“ he developed step-by-step training methods to help guitar players quickly overcome obstacles and rapidly advance your playing to a level you never dreamed possible. 
Steve Stine’s  method is a very powerful and effective exercise, so we decided to put on our lessons. It will improve your playing dramatically. In Steve Stine’s method, you have to change the chords with stopwatch. You start the stopwatch for 1 minute and you change the chords as many times as you can. You can do C to Am change, E to A change and any chords to change in between. At first your score may be 14-15. But don’t give up. Doing this exercise for 1 week results in dramatic outcomes. When you are able to change chord 60 times in 1 minute, you become unstoppable. So keep practicing.
