Even though we encourage early beginning, it is never too late to begin. More and more adults are learning to play an instrument for the first time. It is a myth that children learn faster, my adult students who are committed have time to practice and bring lots of experiences to the lessons that children haven't had. If you have been considering lessons, don't hesitate. Adults need to find outlets to play their instruments to keep up the interest during the beginning stages.
Group lessons are good or just group get-togethers to practice.
Keep it light hearted and try everyday and you will be amazed at what can be accomplished in a few months.
