If there is any musical instrument that can be with you until you get old, guitar is one of the best companions. It is easy to learn, light to carry and you can bring it anywhere. When you know how to play the guitar, it is easy to play music. Playing popular songs will encourage others to sing too. It can be played loud during a sing-along, or you can play quietly under the moonlight while you feel the breeze, just feeling the moment. Start learning early if you still do not know to play. You can check the new used guitar at Musicians Friend if you do not have a guitar yet.
