Circular breathing

Circular breathing is a technique for sustaining airflow from the mouth while inhaling through the nose. It uses air stored in the cheeks to bridge the inhalation.

Buccal cavity: The space inside the mouth, bounded by the cheeks, lips, and teeth. Its temporary air reserve supplies airflow while the lungs refill.
Didgeridoo: An Australian Aboriginal wind instrument traditionally made from a hollowed tree trunk. Its continuous drone is a prominent musical use of circular breathing.
Aboriginal Australian music: The diverse musical traditions of Aboriginal Australian peoples, including song, dance, and instrumental performance. Circular breathing is especially associated with didgeridoo performance in this tradition.
Human respiratory system: The organs and structures through which humans breathe and exchange gases. Circular breathing coordinates oral airflow with ordinary lung ventilation.
Soft palate: The muscular rear portion of the roof of the mouth, which can close the nasal passage during swallowing and speech. Its position helps separate oral airflow from the nasal passage.
Oboe: A double-reed woodwind instrument with a high, penetrating tone. Some oboists use circular breathing to sustain unusually long phrases.
David Blanasi: A celebrated Yolngu didgeridoo player from Arnhem Land in northern Australia. His performances helped bring didgeridoo playing to wider international attention.
Inhalation: The movement of air into the lungs. It occurs through the nose while mouth airflow continues.
Nasal breathing: The movement of air into and out of the respiratory system through the nose. Nasal inhalation refills the lungs while air leaves the mouth.
Saxophone: A single-reed woodwind instrument with a conical metal body. Circular breathing can extend saxophone phrases beyond a single exhalation.
