I'm thinking about getting a trumpet to practice at home for fun. I want to know what type of trumpet is best for me. I'm in 4th grade and need something to do at home. I need to know the difference between the different types of trumpets too. I am a beginner and know nothing about the trumpet. Please respond as soon as possible. Thanks.
First thing to do is find a teacher who can explain things a bit to you. And you absolutely will need a teacher or you'll give up in complete frustration.
Obviously you don't want a medieval straight, valveless trumpet :-) .
Your basic choices are either a trumpet or a cornet. They look almost the same, but the cornet is a bit easier to start out on and is slightly less strident/brash in sound. Then there's fancy stuff such as the flugelhorn or Drum&Bugle Corps-style marching bugles. Leave these for later.
In all likelihood you can find samples of all these variants on YouTube.
You need a Bb Trumpet. If you're offered a Bb Cornet it plays almost exactly the same. If you're aiming to join a certain band (and trumput on its own isn't much use or much fun) contact them now. They'll doubtless have a training scheme, maybe even an instrument loan one. At the very least you'll get good advice and some contacts for obtaining second-hand instruments.
