The cornet's valves allowed for melodic playing throughout the instrument's register. Trumpets were slower to adopt the new valve technology, so for 100 years or more, composers often wrote separate parts for trumpet and cornet. The trumpet would play [[fanfare]]-like passages, while the cornet played more melodic ones. The modern trumpet has valves that allow it to play the same notes and fingerings as the cornet.

Cornets and trumpets made in a given [[Key (music)|key]] (usually the key of B{{music|flat}}) play at the same pitch, and the technique for playing the instruments is nearly identical. However, cornets and trumpets are not entirely interchangeable, as they differ in [[timbre]]. Also available, but usually seen only in the brass band, is an E{{music|flat}} soprano model, pitched a fourth above the standard B{{music|flat}}.

Unlike the trumpet, which has a cylindrical bore up to the bell section, the tubing of the cornet has a mostly conical bore, starting very narrow at the [[Mouthpiece (brass)|mouthpiece]] and gradually widening towards the bell. Cornets following the 1913 patent of [[E. A. Couturier]] can have a continuously conical bore. This shape is primarily responsible for the instrument's characteristic warm, mellow tone, which can be distinguished from the more penetrating sound of the trumpet. The conical bore of the cornet also makes it more agile than the trumpet when playing fast passages, but correct pitching is often less assured.<ref name="American"/> The cornet is often preferred for young beginners as it is easier to hold, with its centre of gravity much closer to the player.

The cornet mouthpiece has a shorter and narrower shank than that of a trumpet, so it can fit the cornet's smaller mouthpiece receiver. The cup size is  often deeper than that of a trumpet mouthpiece.<ref name="EB1"/>

One variety is the short-model traditional cornet, also known as a "Shepherd's Crook" shaped model. These are most often large-bore instruments with a rich mellow sound. There is also a long-model, or "American-wrap" cornet, often with a smaller bore and a brighter sound, which is produced in a variety of different tubing wraps and is closer to a trumpet in appearance. The Shepherd's Crook model is preferred by cornet traditionalists. The long-model cornet is generally used in concert bands in the United States and has found little following in British-style brass and concert bands.

A third, and relatively rare variety—distinct from the "American-wrap" cornet—is the "long cornet", which was produced in the mid-20th century by [[C. G. Conn]] and [[F. E. Olds]] and is visually nearly indistinguishable from a trumpet, except that it has a receiver fashioned to accept cornet mouthpieces.<ref>{{cite web |last1=Derksen |first1=Christine |title=The Long Model Cornet: Fish Nor Fowl? |url=https://cderksen.home.xs4all.nl/ConnArticle9.html |website=The Conn Loyalist |access-date=17 August 2018 }}</ref><ref>{{cite book |title=F.E.

===Echo cornet===
The echo cornet has been called an obsolete variant. It has a mute chamber (or echo chamber) mounted to the side, acting as a second bell when the fourth valve is pressed. The second bell has a sound similar to that of a [[Harmon mute]] and is typically used to play echo phrases, whereupon the player imitates the sound from the primary bell using the echo chamber.<ref>{{cite web |url=http://www.vintagecornets.com/html/echo_cornets.htm |title=Echo Cornets|website=www.vintagecornets.com|access-date=2 May 2018 |url-status=live |archive-url=https://web.archive.org/web/20161110153603/http://www.vintagecornets.com/html/echo_cornets.htm |archive-date=10 November 2016}}</ref>
