Circular Breathing

What it is: A technique where the player inhales through the nose while simultaneously pushing air out of the cheeks through the instrument — producing an unbroken sustained note for as long as the player can keep cycling. Effectively, the player has infinite breath.

What it sounds like: A tone that never stops. Listeners often don't notice — they just feel like the line is impossibly long. Used well, it's invisible. Used badly, you hear the "puff" when the player switches breath sources.

When to use it: Long sustained notes, drones, unbroken melodic lines, didgeridoo-like textures. Modern composers (Glass, Reich, Sciarrino) write phrases that explicitly require it. Jazz players (Kenny G, Rahsaan Roland Kirk) use it for showmanship and extended solos.

Notation: No standard symbol — just write the long note and add "circ. breath" in the part. Some scores indicate it with a box around the passage and a marking like "continuous tone — circular breathing."

Tip: Most professional wind players can do it. Most students cannot. If you write a 30-second sustained note without breath marks, only ask it of pros. For students, write breath rests into the line.

Listen:

Rahsaan Roland Kirk — basically every solo
Sciarrino — solo flute writing (extreme breath economy)
Wynton Marsalis — circular breathing on trumpet (yes, brass do it too)
