When you play a “brass” style instrument (trumpet, tuba, trombone, didgeridoo, vuvuzela, etc) you don’t just blow into it, you press your lips together like for a kiss, and then buzz them. If you do a small, very fast and tight buzz, you get high pitched notes. If you do a looser, flappier buzz, you get low notes. Most people can get about 3 to 5 notes this way, which is why most brass instruments have slides or valves to adjust the airflow and change the note further.
Funny enough for calling this a sax-hybrid, saxophones and other woodwind instruments use a small piece of flat wood called a reed to create the vibrations needed for notes. These mostly only make one note though, which is why sax, flute, clarinet, and so on need so many buttons.
For further clarification, the 3 to 5 in brass notes is because the instruments one vibrate at certain frequencies which are related to the length of the route the air takes through the instrument. The valves, and in case of the trombone the slide, increase the length of the pipe and change the frequency it will vibrate at, changing the tone.
Your lips however can make a lot more notes depending on your ability to control your muscles in your lips.
