RAPa 4-valve

More music,

More artistic possibilities,

More freedom of expression​.


Any LOTUS Trumpet can be made with the Rapa 4-Valve configuration, so you’re free to choose whatever sound you like and still gain access to a whole new dimension of playing


**  Any LOTUS Trumpet can be ordered in the Rapa 4-Valve configuration  **


This is the only 4-valve solution that’s as comfortable to hold as a 3-valve trumpet.  Consisting of 3 pistons and 1 rotor, it’s a superior solution for the 4-valve trumpet as designed by Adam Rapa. Controlling the rotary valve trigger with your left thumb is incredibly easy and feels natural in no time.  

With this design, the 4th valve is an "F-attachment" which gives you 5 more semitones lower than the normal range of the instrument, down to pedal C#.  This is a total game-changer for anyone looking to expand their range and gain access to the wealth of music written for many other instruments, and open up a new world of creative possibilities.​

The Rapa 4-Valve design is also a much more comfortable, elegant solution for players who want a quarter-tone tru
mpet. Alternatively, we can install a special 4th valve (rotor) to be used for dropping every pitch on the instrument by a quarter tone. 

Quarter Tone:
This practical & elegant solution uses the Rapa 4-Valve design, where your thumb triggers a rotary valve that drops any note by a quarter tone.  It’s much more lightweight and comfortable to use than horns with 4 pistons, and using your thumb is so easy, you’ll get the hang of it in no time.

You can add our quarter tone feature to any trumpet model.
