Couple thoughts. Even though it sounds counter intuitive (understanding that placing a capo up the neck will raise the pitch) sometimes the key change actually works better for a lower vocal range
At lease that has been my experience
I have always just assumed I was an upper Baritone
Like Glenn stated I use a capo to find what feels best for my vocal and any particular song
Here I am doing a cover and have the Capo @2 I am playing from the G form so I assume it is in the Key A
