WunderKeys is an innovative program for children including Wunderkeys Piano for Preschoolers for students ages 3-5 and WunderKeys Primer for students 5+.  Individual lessons are adaptable -- at this age, the difference between one 3-5 year old to the next can be quite drastic in terms of coordination, previous knowledge, attention span, number recognition etc.  In a group setting, kids who don't match abilities with the majority of the class don't have as many opportunities to have their individual needs addressed as you can in a one-on-one setting.  This is a little one's very first structured musical experience; creating a solid foundation by enriching and adapting as necessary is so important.
