How long is the air column in a woodwind?

The air column in a woodwind instrument varies in length depending on the instrument and its design. Generally, the effective length of the air column is influenced by the instrument's shape, the presence of tone holes, and the player's technique. For example, in a Clarinet, the air column can be approximately 1 meter long, while in a Flute, it is typically around 66 centimeters. The actual length can change dynamically when holes are opened or closed, altering the pitch produced.
