Hi A.,
I thought I would respond to this, being that I was one of the music teachers at Gymboree until late Oct (when I went on maernity leave - havent gone back yet and am not planning on it for a while anyway, or until they call me to sub!) and I am also certified to teach Kindermusik (I am actually a music therapist so I chose to get paid more for that then be a Kindermusik teacher!).
Anyway, at Gymboree it really depends who your music teacher is - everyone is VERY different. If they go strictly by the lesson plan, then it is a little dry for my taste - I always added some flair to make it not to so cut and paste. I would suggest trying out different music classes/teachers if you can. You will be able to tell a difference! And with Gymboree, there are specific "goals" for each music style, which the teacher should be explaining to you why you are doing a specific activity - like "we are singing this song to introduce melody, imitation, etc etc". With Gymboree, you also do not have to purchase the instruments or props like Kindermusik.
I really enjoyed the Kindermusik plans. I think that Kindermusik is just as well-layed out developmental wise as Gymboree. I don't necessarily see the "clique-ishness" at Kindermusik as I do between the moms as at Gymboree, and sometimes it was somewhat difficult to get the parents involved at Gymboree because they were talking to each other so much about playdates, etc, but I suppose that is true everywhere you go! At Kindermusik, you have to purchase items for the class, but on the upside, they are very sturdy, can be used for long term in the program. I think that in Kindermusik, you get a better understanding of what you can do with your child since you have the bought resources at home with you, so you can just read and listen/interact with your child to the music. With Gymboree, you can purchase CDs with the music on it, but they dont give you too much info as to what to do with it as the teacher is supposed to be portraying it in the class. In the play classes though, they give you a nice long paper to tell you all the info you need! Too bad the music class doesnt have this type of paper!
Pricewise, it depends how you look at it. With Gymboree- you pay the fee per month, and for a few dollars more you can go to all the classes you want/that are offered for your child's age.
With Kindermusik, it depends on where you go pricewise, since everyone is "independent" and can charge however much they want. My friend used to run Kindermusik classes last year and her prices were significantly less then Gymboree, even with purchasing the products.
So, I dont know if this has helped you decide either way, but I guess it can give you some more info!
