Wow, funny I should read this question right now! I just attended a "field trip" with my 5yo to a "Music to grow on class" and it was fantastic!! The instructor is Kathy Lucey and I guess she is very well known for her ability to work with children of all ages to teach the basics of music appreciation, etc. She talked about her classes and said she does different series starting from infant all the way up to teen (so she does have students that have stayed with her all the way thru)Anyway, it was a really cool class with lots of movement, simple instruments, singing voices, etc I highly recommend it and it sounds like your daughter would be a perfect fit!! I saw you are in Aliso Viejo so this would work for you, she teaches in Laguna Niguel and here is a link to the LN Recreation website to see her classes and how to sign up: There is a Music to Grow on class and also one for the family...
