Playing
Fingering
On any modern trumpet, cornet, or flugelhorn, pressing the valves indicated by the numbers below produces the written notes shown. "Open" means all valves up, "1" means first valve, "1–2" means first and second valve simultaneously, and so on. The sounding pitch depends on the transposition of the instrument. Engaging the fourth valve, if present, usually drops any of these pitches by a perfect fourth as well. Within each overtone series, the different pitches are attained by changing the embouchure. Standard fingerings above high C are the same as for the notes an octave below (C♯ is 1–2, D is 1, etc.)
Each overtone series on the trumpet begins with the first overtone—the fundamental of each overtone series cannot be produced except as a pedal tone. Notes in parentheses are the sixth overtone, representing a pitch with a frequency of seven times that of the fundamental; while this pitch is close to the note shown, it is slightly flat relative to equal temperament, and use of those fingerings is generally avoided.
The fingering schema arises from the length of each valve's tubing (a longer tube produces a lower pitch). Valve "1" increases the tubing length enough to lower the pitch by one whole step, valve "2" by one half step, and valve "3" by one and a half steps. This scheme and the nature of the overtone series create the possibility of alternate fingerings for certain notes. For example, third-space "C" can be produced with no valves engaged (standard fingering) or with valves 2–3. Also, any note produced with 1–2 as its standard fingering can also be produced with valve 3 – each drops the pitch by 1 1⁄2 steps. Alternate fingerings may be used to improve facility in certain passages, or to aid in intonation. Extending the third valve slide when using the fingerings 1–3 or 1-2-3 further lowers the pitch slightly to improve intonation.
Mute
Various types of mutes can be used to alter the sound of the instrument when placed in or over the bell. While most types of mutes do decrease the volume the instrument produces, as the name implies, the sound modification is typically the primary reason for their use.
Range
The standard trumpet range extends from the written F♯ immediately below Middle C up to about three octaves higher. Traditional trumpet repertoire rarely calls for notes beyond this range, and the fingering tables of most method books peak at the high C, two octaves above middle C.[contradictory] Several trumpeters have achieved fame for their proficiency in the extreme high register, among them Maynard Ferguson, Cat Anderson, Dizzy Gillespie, Doc Severinsen, and more recently Wayne Bergeron, Thomas Gansch, James Morrison, Jon Faddis and Arturo Sandoval. It is also possible to produce pedal tones below the low F♯, which is a device commonly employed in contemporary repertoire for the instrument.
