More music. More artistic possibilities." More freedom of expression.
All LOTUS trumpets can be made in the Rapa 4-Valve style


The only 4-valve horn that is as easy to hold as a 3-valve
An option that offers all the advantages of the LOTUS trumpet, but with a wider range!


Consisting of three pistons and one rotary, this is the complete 4-valve trumpet designed by Adam Rapa. Controlling the trigger of the rotary valve with your left thumb is very easy and you will get used to it in no time.
Simply play your favorite scale studies in that range with slow metronomic precision and you will be amazed at how technical you can become.

The tube of the fourth valve is wrapped snugly around the valve block, keeping the instrument perfectly balanced. It is very natural and comfortable, and there is no need to change the way you hold the instrument.
This design is revolutionary for anyone who wants to expand their range, connect to the wealth of music written for other instruments, and open the door to new possibilities. Once you have been exposed to this type of 4-valve trumpet, you will never go back.
