What's good about Kindermusik for big kids?

I can't say enough about Kindermusik for 3 1/2 to 8 year olds (Kindermusik Imagine That! and Kindermusik Young Child). My goal is not to prepare them for school like the graph below suggests (click on it to read the study in detail). But my own goal is nurturing creativity, thinking, musicality, and joy. I do work them hard and I am so proud of my Kindermusik "graduates". They can read music...they can look at a sheet of music notes and hear the tune of it in their heads! They know key signatures, meter signatures, syncopation, ledger lines, musical form, they can read and play one rhythmic line while two or more contrasting lines are being played simultaneously, they know the instruments of the orchestra, ......They are amazing. Every year I am simply blown away. Area private teachers continue to tell me they love those Kindermusik graduates because they really fly through the first few books....And another thing: Parents of Kindermusik graduates really understand the imortance of their support and involvement in this musical journey. It really pays off and in more ways than one.Thank you for sharing your children with me. I love them.
