I was wondering if I have a friend who knows how to play mandolin, because, my youngest son asked me if I have a friend who knows how to play this kind of musical instrument. His teacher picked him up to join the stage play in the school, and he needs to play a mandolin. My son played a guitar so well that is why he was chosen to play the mandolin. However, he has a problem because no one of his friends knew how to play mandolin, so we have to find a mandolin beginner guide, so he could practice it all by himself. Anyhow, the play will be in December, so, he has plenty of time to practice playing this kind of a guitar.
