Singing From The Diaphragm
I figured out the last piece of the puzzle today right before my recital tomorrow. I am got my vibrato back in a different coordination than what my previous teacher taught. It's all with the diaphragm. You had to be able to get yawning right to access it. I don't sing flat and the notes sound really good even if I mess up. I can sing in my full tenor range. It's like you coordinate the diaphragm movement with singing. I didn't realize how big of a difference in sound it makes tell now. It's a night and day difference.
