Earlier this month we were in a beautiful tent overlooking the valley from Kirurumu Manyara Lodge. At 5:30am I awoke to beautiful singing/chanting coming from the valley. I went out on the patio of the tent and listened to it. It was over by 5:45am. It sounded more like male voices. Later that day I told my guide about it and asked if it was some type of morning prayers. He said he thought it may have been people on their way to work. I have googled it and can not come up with anything. Has anyone else experienced this? It is a lovely memory of our trip, and I'd like to know if the singing had any particular significance.
