    The flute is a musical instrument of the woodwind family. A flute of smaller length produces waves of higher frequency. Sound waves travels through medium even through extremely dense medium like rocks in the form of longitudinal waves only. A good example is the shock wave from an Earthquake, which can be heard hundreds of miles away from the epicenter after travelling through rocks in the ground.
