player's lips.
Sound is produced by placing the lips on the mouthpiece and blowing while vibrating the lips. The larger the mouthpiece, the lower the sound of the instrument. By tightening or loosening the lips, it is possible to produce different notes, but only so many notes can be produced this way, so you press down the valves to create more notes. See related link for more information.

by blowing into the mouthpiece creates a vibration the send sound to the valves, then its up to you how high/low the sound is depending on the valves pressed and how your tight your mouth was. then the sound projects throughout the tuba and out the bell.
The Wagnor tuba and the American french horn are identical instruments. Their construction and sound are identical.
