I have been playing an Alto and Soprano Sax for about a year. Just got an old Trumpet from Ebay, An 'E.K. Blessing' from Elkhart In. It had a split down what I think is called the leadpipe. Just after the part where the mouthpiece attaches. I patched it with clear packing tape and it seems to be holding the compression. I got a few sounds out of the horn, that I would call C, D, E, F, and G, when I am blowing at a moderate rate. When I try to increase the volume by blowing a little (Faster/Harder), the C, and D, sound pretty good, but when I press the 1 and 2 valves for the E, the sound doesn't change, the sound (F) will sound but not great, going from the 1/2 to the 1. then when I open all valves the sound just is destroyed, unless I apply a lot of air. Any suggestions, Do I still have compression problems in the valves? Is it just me with my lack of experience? Is this common to beginners? Thanks, George PS: I am having a blast trying to make sounds with this horn.
