Breathing for singing is all about how you are regulating your air
You want to build muscle control as you exercise
Begin to project your voice based on what you feel, not just on what you hear. You want to feel how to breathe properly, where your voice is resonating etc.
– visualize the air filling the space between your navel and your sternum (where your diaphragm is)
– visualize spending your breath evenly across a whole phrase. Use your abdominal muscles, connected to the diaphragm, to apply a good amount of pressure to control your outflow of air.
