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]].

Each [[overtone]] series on the trumpet begins with the first overtone—the [[fundamental frequency|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 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.<ref>{{Cite book |last=Pagliaro |first=Michael J. |url= |title=The Brass Instrument Owner's Handbook |publisher=[[Rowman & Littlefield]] |year=2016 |isbn=978-1-4422-6862-3 |location=Lanham, Maryland |pages=37–39 |oclc=946032345}}</ref> 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 {{frac|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.<ref>{{Cite book |last1=Ely |first1=Mark C. |url= |title=Wind Talk for Brass: A Practical Guide to Understanding and Teaching Brass Instruments |last2=Van Deuren |first2=Amy E. |publisher=[[Oxford University Press]] |others=Amy E.

Some of the partials of the [[Harmonic series (music)|harmonic series]] that a modern B{{music|flat}} trumpet can play for each combination of valves pressed are in tune with [[12-tone equal temperament]] and some are not.<ref name="utc">{{cite web |last1=Schafer |first1=Erika |url=https://blog.utc.edu/erika-schafer/trumpet-tuning-tendencies-relating-to-the-overtone-series-with-solutions-2/ |website=UTC Trumpet Studio |title=Trumpet Tuning Tendencies Relating to the Overtone Series with Solutions |access-date=19 January 2023}}</ref>
