RAPa 4-valve

**  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 trumpet. 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.
