What is the difference between a saxophone and a trumpet?

The main difference between a Saxophone and a Trumpet is their shape and sound production. A saxophone has a conical shape and uses a single reed to produce sound, while a trumpet has a cylindrical shape and uses a mouthpiece with a small cup and a buzzing player's lips to produce sound. Additionally, the saxophone has a wider range of notes and a mellower tone compared to the brighter and more piercing sound of the trumpet.
