Thank you for your post! We are glad to hear that you are enjoying My First Piano Adventure. Though the course was designed for 5-year olds, it could be adapted for preschool age children if taken very s-l-o-w-l-y with lots of parental involvement. We would recommend the introduction of songs through singing with and without the CD, lots of movement with the CD, and conversations about the friends at the piano characters in the book to meet the playful spirit of this young age group.
