I have a yamaha cornet and i took the valves out to oil them. i put the valves in, and now only the middle on makes a sound. when i put down no valves, and doesn't make a sound, only when i press down valve two. i think it is the way i put the valves because it has those holes. can some one let me know what is the right way to put the valves in, like explain or show me a video. thanks.
Every trumpet I've used has numbers on the valves. These should be facing you when inserting the valves, valve 1 being closest to you, and valve 3 being closest to the bell.
I play a baritone, but I hope I can help. On my instrument there are little notches at the tops of the valves. I had to spin my valve until I heard a slight click then I would push down on the valve to make sure it worked. (I would start on the first valve) Then to make sure that I had it in right I would blow in the instrument to see if the air went through the holes. Try that, it might help. Also, the next time you take your valves out keep them in order and in the position they came out in.
