I'm a little confused as to how to breathe properly while singing because I've found I'm able to both inhale with my belly expanding or going in and to exhale with my belly expanding or going in. What is the proper way to breathe while singing?

Hi, Sandra! We do recommend inhaling with the belly expanding, as that follows your body's natural process (lungs expanding, diaphragm lowering). I encourage you to search for lessons here on the site & our YouTube channel for more guidance and exercises!
