@j-jericho Thank you. Interesting experiment here: can an online community guide me into appreciation of a new art form in a way that the Real World (TM) cannot. I suspect so, based upon the kind assistance offered in this thread. And without the condescension one would expect to encounter our there in the so called RW.

Hey I just picked up a used Ambassador on CL. WOrks fine. But I have no clue even which youtube lesssons to start with. It's a little embarassing being a complete newbie but I love the tones I get.

Actually I am afraid to play the new one until I figure out whether or not it is properly lubricated. Someone somewhere warned me you can ruin a trumpet that has been sitting if it is not properly lubricated.
So for now I am afraid to touch it. It is just sitting there. I did pick up a sax, but it does not have that same trumpet effect that I enjoyh, using the diagr]phragm and really putting some umph into it as only trumpet acheives.

I am a beginner. I have a trumpet for which one of the valves does not do anything. You can press it down but it does not modify tone in any manner. The other two seem to function reasonably well. I want to get going and start practicing with all three valves is there anything I can do short of taking it in for an overhaul which may cost as much as a used trumpet in better condition?
