A sister in our ward sang in our Sacrament meeting with her daughter and granddaughters. One of her granddaughters is hearing impaired, and her singing involved signing the song. This was the second time I have seen her sign with a group of singers and both times I have found it inspiring. The way she moves her hands and arms is so rhythmical and fluid, it adds another dimension to the song. You can actually see what the song sounds like.
