We've had the CDs in this boxed set for over a year now. The Classical Kids series has been wonderful. We have two boys (now 6 and 8) and this has been a great introduction to classical music. At first, the kids loved the stories which provide a sense of history and place and, ultimately, keep the kids interested in the entire CD. As they listened (time and time again), they started to pay more attention to the musical portions. Recently, we've been able to tell that they've picked up a sense of the music as we've listed to classical music on the car radio. Time and again, they perk up when listening to a piece of music and surprise us by saying "That's Beethoven". Sure enough - they've picked up something about the style of music that's characteristic of Beethoven. Sometimes it's the snippet of music from the CD and other times it's just the rhythms that are characteristic of that piece. As a family, we all recommend this.
