The first step in helping a client with breath control issues is to identify the root cause, which can be physical, mental, or emotional, or a combination of them. Common causes include poor posture and alignment, tension in the jaw, neck, shoulders, or chest, lack of awareness and coordination of the breathing muscles, habitual shallow or fast breathing, anxiety, stress, or nervousness, and vocal fatigue or damage. To assess your client's breath control, you can use various methods such as listening, observing, asking questions, and measuring. For example, you can ask your client to breathe normally and notice how their chest, ribs, and abdomen move; hold a note for as long as they can and time them; sing or speak a phrase and mark where they take breaths; and rate their level of comfort, confidence, and ease with their breathing.
