You cannot force someone to do something if they feel that their heart do not belong to it. This is the same manner when we want our children or kids to learn to play guitar, which could be tasking and demanding if their heart is not into it. Everything is being sparked with a simple desire and exposure. In most cases, some of the self-confessed and self-taught players who have made an effort to do it on their own, without the assistance of anyone have tried it by themselves, did succeed although there are mistakes along the way.
Exposure is the key to really learn 2 play guitar and not just buying your kid a gift and have it taken for granted. In fact, most of them would have that inner desire once you bring them to recitals, concerts, and let them watch videos online about kids who play and enjoy guitar. From those simple activities, you will discern if your kid would develop a strong liking and connection with music, especially with playing the guitar.
