I'll second the Music Together recommendation. We did a year of MT through Arlington Rec with both our children in their early years and it was money well spent. There was a different Arlington Rec music class (can't remember the name) that we tried once when the MT classes were all full, but it was painful for us parents. We ended up asking for a refund rather than go back. Stick with Music Together and you should be satisfied, though I will note that while the MT program is great, a lot depends on quality, singing voice, and enthusiasm of the teachers.

We are looking for something in NW -- near Cleveland Park during the week, or anywhere if it's on a weekend. What have people enjoyed?
