The “Fast” Circular breathing method
Bounce Breathing is a type of circular breathing that is separate from using your cheeks to store and push air out during inhalation. Although it is often perceived as an advanced circular breathing method, it can be learned first and may occur to some players as easier than the cheek method. this style of breathe allows fast rhythms to be payed with breathe control as well as quick breaths on top of trumpet notes.
