Asthmatics and anxietals, beware of Singing Teachers that force you to “breathe quietly” in your first vocal lesson. This will be extremely dangerous to your health.
Firstly, you must tell them what you are dealing with, because these two challenges will directly affect your ability to “let the breath drop in” during your inhalation, and your ability to exhale during phonation.
These two afflictions will also have affected your posture and your confidence, also extremely important in performance skills.
