When the director of an orchestra wants to know the correct tone height, he takes his tuning fork out of his pocket and hits it to his lectern. Although the tuning fork is only excited during a very short time, it can be used as an extremely accurate frequency reference. Due to the lack of any amplifying components, the frequency only depends on the mechanical properties of the high-Q resonant tank. When a small flute is used instead, the tone height is affected by the applied air flow, which results in a less accurate frequency reference.
