Trumpet fingering

On any trumpet, cornet, or flugelhorn, pressing the valves indicated by the numbers below will produce 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 concert pitch which sounds depends on the transposition of the instrument. Engaging the fourth valve, if present, drops any of these pitches by a perfect fourth as well. Within each overtone series, the different pitches are attained by changing the embouchure, or lip position and tightness, along with increasing air velocity. Standard fingerings above high C are the same as for the notes an octave below (C sharp is 1-2, D is 1, etc.).

Note that the fundamental of each overtone series does not exist - the series begins with the first overtone. 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 schemas arises from the length of each valve's tubing (air passing through longer lengths of tubing 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 schema 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. Extending the third valve slide when using the fingerings 1-3 or 1-2-3 further lowers the pitch slightly to improve intonation.
