Granduncle Plays Guitar for His Quadruplet Grand-Nieces and Nephews

"The only thing more healthy than seeing a child listening to music for the first time is that a loving family member serenades him. In this video, a five-month quad band sits on a piano while his uncle plays a soft, low acoustic guitar for his delight. The children nod, shake their heads and shake with approval during the thirty-second video. The video has accumulated 13 million views since it was released in 2010. The video appears on a YouTube channel called Four By Two. The parents of the four children started the channel to tell the story of their children's lives as they grow up.
