lol. So, are the sixteenth notes hard on a trumpet and are the fingerings hard as well?
Not really, you only have three valves. You rarely touch any other moving part after the first time.
You should be able to pull the valves out by un screwing the cap under the thing that you push down on. And it should slide all the way out just apply the oil to the outside of what comes out. that way it slides better.
Let me get a image for you
