In the video , Chord C Major is played with a simple strumming.
Now, try this on your guitar!!! It's not very easy so playing a chord can't be accomplished first up rather it depends on your practice, you know what they say Practice makes perfect. This phrase is just about perfect for learning and playing guitar.
See you in the next lesson where we'd be learning up a few exercises to improve your over all base to play the guitar well. The examples would be given with illustrations and videos and detailed account would be given there. So stay learning !!!
