I would say one of my biggest weaknesses right now is my inability to perform some phrases correctly due to lack of air. Is there a way to increase the amount of air you can hold in your lungs, or does the ability to maintain a long phrase come from airflow control alone? If the former, do you know any exercises to do so? I've seen products for brass players to practice breathing without the mouthpiece or the instrument; would those be of any help?
