No, no way - the Children, Men and Elves alike, were in the Music, but:

So they were there, only not in the beginning. Where I believe (or would conclude, by logic) that the Dwarves were not in the Music, because Aulë got the idea of creating them only when he saw that there are still no Children coming and the world is quite empty (or so he felt). So, in the Music, Aulë was probably singing about stone and gems and metals and whatever, but not about Dwarves.
