Like the trumpet and all other modern brass wind instruments, the cornet makes a sound when the player vibrates ("buzzes") the lips in the mouthpiece, creating a vibrating column of air in the tubing. The [[frequency]] of the air column's vibration can be modified by changing the lip tension and aperture, or [[embouchure]], and by altering the tongue position to change the shape of the oral cavity, thereby increasing or decreasing the speed of the airstream. In addition, the column of air can be lengthened by engaging one or more valves, thus lowering the pitch. [[Double tonguing|Double and triple tonguing]] are also possible.

Without valves, the player could produce only a [[Harmonic series (music)|harmonic series]] of notes, like those played by the [[Bugle (instrument)|bugle]] and other "natural" brass instruments. These notes are far apart for most of the instrument's range, making [[diatonic and chromatic]] playing impossible, except in the extreme high register. The valves change the length of the vibrating column and provide the cornet with the ability to play chromatically.<ref name="EB1"/>
