This is a great experiment for me. I really can't sing. I can not carry a tune very far, not even happy birthday! I think there is potential however.
I can follow other voices in unison in my range which is baritone. I play piano and bass guitar which can help support my vocal efforts in many ways. Lastly I do not play professionally, just a life long hobby.
It will be interesting to see if I can achieve even a Bob Dylan, Tom Waits, Leo Kottke, Doc Watson or similar.
Working on breathing, I get light headed with the lip rolls which I am just beginning to try. This is probably normal at first but just checking to see and if there are ways to minimize it. Is it normal? Does one get into better aerobic shape with these exercises?
