The trumpet is a brass instrument, usually coloured gold. It's a little more than a foot long, with three valves that are pressed to create different pitches. It's usually the trumpet in a band or orchestra that will have a solo, besides the flute. It has a range of about two octaves, and most beginners are started on the lower one and taught to go higher. Many of the fingerings are the same for different notes, and just the tightening of the eumbachoure makes the note different.
To the BeginnerEdit
Yes, your lips will get hot and tired and red very quickly the first time you pick up the instrument. Don't be worried if you have trouble making a sound, and if you have to puff out your cheeks to get a sound at first, just try not to get into a habit of it. That's the one thing many beginners have trouble with: keeping their cheeks in. And without practice, it will be very hard for you to get higher than a G, usually the fifth note you'll learn, depening on your program. One thing that will help you is a mouthpiece with a larger hole. Many pros will use a mouthpiece with a thick outer-wall, bit small hole to pucker-up on.
