Which trumpet valve goes where?

There are three valves, or pistons, on a trumpet; the first, second and third. The first valve is closest to the player holding the horn and the third valve is closest to the bell. The second valve is in-between the first and third. At the top of each valve is the finger button, which is screwed onto the valve stem.

How do you fix a trumpet valve that wobbles?

Things You'll Need:

Remove the loose trumpet valve by turning the top valve cap counterclockwise. Pull the valve straight up and out of the valve casing. Turn the trumpet upside-down to allow the spring to fall out of the valve casing. Measure the length of the spring.
