The trumpet is a harmonically tuned instrument typically designed to play music written in [[12edo]]. In a standard trumpet, this is achieved by a root pitch within the harmonic series, and three valves, which respectively lower the pitch by either two semitones, one semitone, or three semitone. By combining the three valves, the trumpet can semi-accurately play notes in 12edo (with a basis of a certain [[Just intonation]] due to its reliance on the harmonic series).

Certain notes (especially notably, the low C# or Db) have poor tuning due to this design and must be adjusted with a trumpet's adjustable valve tuning slides. For most trumpets, all three valves can be retuned; the first and third can be retuned in real time.

While uncommon, there are quartertone trumpets available for purchase or commission. Notable trumpets include the Adams A4, a jazz trumpet which can be ordered to include a quartertone valve. Additionally, CarolBrass sells quartertone trumpets.

Professional-grade trumpet "techs" are known to have created rotary valves which attach to the main tuning slide that lower the pitch of the trumpet by a quartertone.  
CarolBrass also sells commercial quartertone trumpets.  


Ibrahim Maalouf partnered with AJ Atelier des Cuivres to commercially sell the "[https://aj-atelierdescuivres.fr/produit/trompette-a-jaminet-toma/ TOMA trumpet]," a quartertone trumpet which Maalouf now uses exclusively.

[https://www.pujetrumpet.com/ Pujé trumpets] are built with directly adjustable slides on the main tuning slide. According to Brent Peters, however, the slide is "hard to use accurately and quickly enough" [to play quartertones], "even with a trigger."
