INNOVATION AND EVOLUTION
To the advantages of a D/E flat trumpet, the fourth valves add a broader register and a bigger sound, so that you can play repertoire only reserved to lower trumpet, but in a lot more comfortable way. Also, thanks to the fourth valve, the “cadenzas” in the concerts written for the E flat trumpet, have suddenly a lot more possibilities.

By changing the slides and the leadpipe, the Eb trumpet becomes a D trumpet
 
The fourth valve enlarges the low register of the trumpet and provides magnitude and density to the sound
