A glissando, a sliding sound without stopping at different notes. It is produced because a trombonist can put the slide in between the positions allowing a smooth transition between notes with out skips that would be produced by a trumpets valves.
okay first of all it noise not nose because a trumpet cant make a nose!! and second go buy yourself a trumpet then blow in to it and you will make a sound! that is how a trumpet makes a noise!!:)

It could be several things. There could be a crimp in the tubing somewhere or there could be something stuck in the tubing.
You can read a triad but... You cant play a triad with a single trumpet. Its a monophonic instrument.
You cant
well look for it if you cant find it then push bottens
Nowhere
It was made by Selmer and is a Strad 37 clone but with a two piece bell. It was the intermediate below the Bach Strad but you cant really comment on a trumpet unless you can play it. Quality wise it was a well made instrument. The sound was a bit brighter than the Strad. A good student step up instrument.
i need sound on skype
To play high notes you have to tighten your lips and blow hard
Sound can.
Personally I would take it to a shop right away. If you cant get it out, remember the more you try, the more it might hurt the trumpet. If you take it to a music shop, it should be a simple fix.
