Why do trumpets and flutes sound so different?
Two Voices, One Breath
Why do trumpets and flutes sound so different?

You blow air into both. You use your fingers on both. So why does a trumpet sound like a bright fanfare while a flute sounds like a soft whisper? The secret lives in what happens to the air inside.
When you blow into a trumpet, your lips buzz against the mouthpiece — like making a "raspberry" sound. That buzzing chops the air into fast vibrations, and those vibrations race down the tube. The trumpet is just a long metal megaphone that makes your lip-buzz LOUD.
