Tody I'm going WAY back...this is a photo of my Great-Grandmother Bunn. This photo was taken in Laredo TX, most likely in the 1920's.
She was a very talented woman who played the piano, wrote music, sang beautifully and danced often. She found that children are more calm, and learn better when there is soft music playing in the background. In her later years, she petitioned the schools to play soft music on the overhead speakers during class.
When I was in school in Texas, we still had soft music playing on the speakers during our classes, I don't know if they do it anymore.
Go dig out some old photos and memories to go along with them!
