Breathing…the perpetual confusion
Whether we should breathe with our noses or our mouths during singing is a constant query. Briefly, breathing through your nose activates the nerves that control the intercostal (rib) muscles so that you can take a deeper breath than through your mouth. The amount of air is actually double that of mouth breathing.
However, singers know that there isn't always time to do more than gasp a quick mouth breath in order to continue a fast or long passage. Dilemma! The solution is simple, of course...Whenever you have a rest, that is long enough to do so, take a relaxing, refilling nose breath. When you cannot, take a quick mouth breath.
