Answer 1

Concert Tuba-A "sit down" tuba, the one you see most often, has 3-4 piston or rotary valves, can use a mouthpiece attachment to carry on the shoulder for marching.

Sousaphone,- the "tuba" for marching that rests on your shoulders

Contra- another type of tuba for marching, looks like a tuba, and is put on the shoulder, lighter than a regular tuba
