A person has mass, and that mass is attracted to the mass of another person. But this attractive force is small because of the small mass of the people. The earth, on the other hand, has a lot of mass compared to that of a person. And it will pull that person to its surface.
The baritone saxophone, like other saxophones, is a conical tube of thin brass. It has a wider end, flared to form a bell, and a smaller end connected to a mouthpiece. The baritone saxophone uses a single reed mouthpiece like that of a clarinet. There is a loop in the neck to reduce it to a practical height.
Tuba - The tuba is deep-sounding and is the largest instrument of the brasswind family. Like the trombone, music for the tuba can either be written in the bass or treble clef. Although it doesn't require as much lung-power as the trumpet, the tuba can be difficult to handle due to its size.
