The flute is the smallest and highest pitched beginning band instrument. It is a member of the woodwind family even though it is made of metal and doesn’t use a reed to create the sound. In order to produce a tone on the flute, the player blows across the tone hole of the mouthpiece, allowing the air to split at the far edge of the hole. That creates a whistle sound. It uses the same principle as a whistle or blowing across a soda bottle. In all cases the air splits to create a sound. Aiming a thin air stream at the edge of the hole to make a sound can be a bit challenging at first but it gets much easier with time and practice.
