Why does the saxophone not belong to the brass family?

Answer 1

The saxophone has a reed, as well as the woodwind. The brass family does not use reeds. That's why it doesn't belong in the brass family

Answer 2

The Saxophone is actually a member of the woodwind family because it produces sound through a reed vibrating against the mouthpiece, similar to other woodwind instruments like the Clarinet. While it is made of brass, its classification is based on its method of sound production rather than its material.
