Mom Bar means “candle dance”, and there are several of them in the Armenian world. This particular Mom Bar was still being danced in Armenia in the ’90’s. It is the final dance of a 3-day wedding celebration. When the groom leads this dance, it’s a tacit message that the party is over. Unfortunately I have no link to a video of this particular Mom Bar, as taught by Tineke van Geel.
Here’s a couple of links to a simpler Mom Bar.
Same music, but with photos of Armenia.
For yet another, see Mom Bar under 2nd Generation dances.
