What makes a oboe work?

An oboe works due to the principle of sound production known as the Bernoulli effect, which states that when a fluid (such as air) moves faster, the pressure exerted by that fluid decreases. In the case of the oboe, the player blows air through a small opening called the reed. This causes the air to move quickly and create a low-pressure area inside the instrument. The surrounding air then rushes in to fill this low-pressure area, causing the reed to vibrate. These vibrations create sound waves, which are further amplified and shaped by the oboe's body.
