Brass instruments compensate for fixed valve lengths with player-adjustable tuning
Evidence
In practice, on a trumpet, for example, the third valve is often fitted with a tuning slide so that the player can alter the added pipe length while playing. No such issues arise for the trombonist, who can alter the slide position accurately — David M. Howard, Jamie Angus, Acoustics and Psychoacoustics, 1259
