Each time you press a key on a brass instrument then blow into the mouthpiece that key that you have pressed down is compressing the air which leads to a note A, B, C, D, E, F, G.
Pressing down the valve increases the length of the tube. Valve #2= ½ step, #1=1 step and #3=1½ step. The length of the tube determines the pitch of the sound. The valves all open will play (B-flat horn) a C, G, C'.
If you play a C and, with your embouchure the same, press down the 2nd valve your pitch will drop to B...press 1 and your pitch will drop to B-flat. Press 1 and 2 together and you drop the pitch to A.
If you start at G (all open), 2 is an F#, 1 is F, 1&2 (or 3) is E, 2&3 is Eb, 1&3 is D, 1&2&3 is C#...Then you are back down to C with all valves open.
Important note is that the fingerings he is stating are for Trumpet. Other brass instruments have different fingering for those notes but regardless the valves drop chromatically the same amount
Meaning that 2nd valve drops one half step on all brass (except Trombone)
1st valve is one whole step
1st and 2nd together(or third alone) is 3 half steps
2nd and 3rd valve together are 2 whole steps
1st and 3rd together or 4th alone are 5 half steps
1st 2nd and 3rd together or 4th and 2nd together are 3 whole steps
1st and 4th together are 7 half steps
1st 2nd and 4th together are 4 whole steps
2nd 3rd and 4th together are 9 half steps
1st 3rd and 4th together are 5 whole steps
1st 2nd 3rd and 4th together are 11 half steps
Some concert instruments have more than 4 valves, more with only 3.
also note that with a 4th valve you can go nearly an entire octave while on the same partial (a partial is the base note you start with, open/no valves pressed).
When the keys are pressed the valves move down in the cylinder. The valves are like round metal tubes that have holes drilled through them. When the valve moves down, the holes line up with two opposing brass tubes and lets the sound pass through.
It's a complicate combination of pushing keys to make the valves go up or down. A spring is located at the bottom of the metal valves to push them back up when the keys are released.
If a brass instrument was stretched out without the curves in it, it would be so long that it would not be feasible. Everyone has seen those trumpets in movies depicting the Romans where they play as the army triumphantly enters the city
The longer you make the tube with valve combinations, the lower the fundamental tone. The lip is used to play harmonics of that fundamental.

Which brass instrument is built with rotary valves?
I'm no brass instrument, but rotary valves are used for several instruments. French horns all seem to have them. They're pretty common on tubas as well. There are even some rotary valve trumpets out there. I don't know, though, anything about the advantages and/or disadvantages of rotary valves as opposed to the piston valves that seem to be more common for most brass instruments.
Did all brass instruments have three valves long ago?
Valves for brass instruments weren't developed until around the year 1800.
What are the keys on brass instruments called?

Which member of the orchestal brass family not have valves?

What was made in1815 that allowed Brass instruments in orschesta?

how do valves work on brass instruments?
The way the valves on a brass instrument work is that when pressed down they allow air to pass through a piece of tubing, thus making the length of tubing of the trumpet longer, this allows valved instruments to be able to play more notes than instruments without valves.
Why do brass instruments have valves?

What brass instrument has no valves?
The brass instrument that has no valves is the trombone. Instead of valves, it uses a sliding mechanism to change pitches, allowing for a smooth transition between notes. This unique feature distinguishes the trombone from other brass instruments that utilize valves to alter their pitch.
