Peer review

The article is good, very complete and succinct. The tone is objective and clear, as Chris had insisted.

Although it would perhaps not be necessary for an ordinary wiki, for the purposes of this course it might be useful to include more information on the physics of the quality/variations of brass. It looks like you're getting there with the unfinished portion of the article.

"Trumpet, trombone - cylindrical bore Horn, Tuba, Euphonium - conical bore

Cylindrical bore = brighter, more piercing sound Conical bore = mellower, warming sound"

That portion of the article is a bit awkward and bare bones for the format of a wiki.

if you can find it, a sound clip or video demonstrating the different tones would be a nice addition.
