Not a very clear question.
Do you mean what are some examples of brass instruments? Or what parts of the brass instruments are used to create the different pitches? Or what parts of a person's body does he use when playing a brass instrument?
Please rephrase. Or better yet, since you're doing a research project, do a google search on something like "brass instruments" - you'll get about a million sites that will provide you with all the info you need.
