* Embouchure: The embouchure is the way in which the player's lips and facial muscles are positioned on the mouthpiece of the trumpet. By adjusting the embouchure, the player can change the pitch of the note being played.
* Air pressure: The amount of air pressure that the player applies to the trumpet also affects the pitch. Increasing the air pressure will raise the pitch, while decreasing the air pressure will lower the pitch.
* Slide: The slide is a movable section of tubing on the trumpet that can be extended or retracted to change the length of the instrument. Extending the slide will lower the pitch, while retracting the slide will raise the pitch.
* Valves: The valves on the trumpet are used to change the length of the tubing by opening and closing different sets of valves. This changes the pitch of the note being played.
* Fingerings: The fingerings used on the trumpet also affect the pitch. Each fingering combination corresponds to a different note.
By combining these different techniques, trumpet players can produce a wide range of pitches.
