Ujjayi
Ujjayi is often called the "sounding" breath or "ocean sounding" breath, and somewhat irreverently as the "Darth Vader" breath. It involves constricting the back of the throat while breathing to create an "ah" sound -- thus the various "sounding" names.
Dirgha Pranayama Known as the "complete" or "three-part" breath, dirgha pranayama teaches how to fill the three chambers of the lungs, beginning with the lower lungs, then moving up through the thoracic region and into the clavicular region.
