How does saxophone makes higher pitch?

The Saxophone produces higher pitches by shortening the vibrating length of the air column inside the instrument. This is achieved by pressing down the keys, which open specific tone holes, effectively reducing the length of the path the air travels. Additionally, the player can control the pitch by adjusting their embouchure and airflow, allowing for greater variation in sound. The combination of these factors enables the saxophone to reach a wide range of pitches.
