What is Mouthpiece (brass)?
[[Image:Trumpet mouthpiece 2.jpg|300px|thumb|A [[trumpet]] mouthpiece]] A ''' brass mouthpiece''' is the part of a [[brass instrument]] that a player blows into to make a sound. The purpose of a mouthpiece is to send [[vibration]]s down the instrument to make a [[note (music)|musical note]]. Larger mouthpieces are used on larger instruments, and smaller ones are used on smaller instruments. This is because a larger mouthpiece makes a lower sound, and a smaller mouthpiece makes a higher sound, and bigger instruments make lower sounds and smaller instruments make higher sounds. == Different parts of a brass mouthpiece == [[Image:Trumpet mouthpiece cut-away numbered.svg|thumb|The different parts of a [[trumpet]] mouthpiece.<br>Part 1: Inner rim<br>Part 2: Rim<br>Part 3: The contour, or shape, of the rim<br>Part 4: Rim edge<br>Part 5: Cup<br>Part 6: Throat<br>Part 7: Backbore<br>Part 8: Shank]] A mouthpiece has many different parts, and all its parts have different names. *Rim - The ''rim'' of a [[trumpet]] mouthpiece is the part that makes a circle at the top of the mouthpiece, and is the part that is in physical contact with you when playing.<ref>{{Cite web |url=http://www.westmusic.com/content/index.php?option=com_content&task=view&id=94&Itemid=144 |title=Facts about parts of a brass mouthpiece |access-date=2007-10-10 |archive-date=2007-10-30 |archive-url=https://web.archive.org/web/20071030142619/http://www.westmusic.com/content/index.php?option=com_content&task=view&id=94&Itemid=144 |url-status=dead }}</ref> *Cup - The ''cup'' of a mouthpiece is the part inbetween the rim and the back bore.
