I've never done breathing exercises before and have just started after about a year of singing.
I know "breath control" is seen as very important but how specifically will such exercises improve my technique and skills? And over what kind of time-frame?
As a baseline I can currently inhale for about 5s, and exhale or sing a note for about 20s. I definitely don't feel I'm able to inhale very deeply especially through my nose - I notice this when swimming too. So as well as how exercising will affect my singing, I'm curious how my ability to perform such exercises will improve over time too.
