Reed vibration frequency depends on reed, air column, and coupling

Evidence

Assuming for the moment that the airway of the player is merely a source of steady pressure to drive the reed, the reed vibration frequency will be determined by (1) the reed’s natural vibration frequency, (2) the resonances of the instrument air column, and (3) the strength of the coupling between them. — Eric J.
