Although it somewhat resembles a cornet, the Schagerl Raweni is unmistakably a trumpet. Its design was born from the desire to have a rotary valve instrument due to the different articulation achieved compared to piston valves. The rotors offer a more precise sound with less downtime between notes, which is particularly noticeable when playing fast in the upper register.

Rotary valve trumpets differ from their piston counterparts: the leadpipe of a rotary valve trumpet is very short, running directly from the mouthpiece to the first rotary valve. In contrast, a piston trumpet's leadpipe is almost four times longer, extending towards the bell and then returning to the third slide. This difference in leadpipe length significantly affects the trumpet's sound and feel, especially in the upper register.

Thus, the Raweni was designed as a rotary valve trumpet with a piston trumpet leadpipe. This led to the creation of several prototypes with different shapes and configurations until the magnificent production model was achieved. There is still a leadpipe that extends to the first rotary valve (like all rotary valve trumpets), but only after a long journey to the bell, which returns towards the mouthpiece, resulting in a length similar to that of a piston trumpet.

The 'cornet appearance' is due to the rotors being placed at the bottom (increasing the vertical dimension), resulting in a reduction in horizontal length, similar to a cornet. But in terms of tubing, it is indeed a trumpet. The body, which resembles pistons, was placed on top so the instrument can be played with one hand. This means the Raweni is played 'straight' like a piston trumpet, rather than sideways like most rotary valve trumpets. In this regard, the Raweni is similar to another wonderful model by Schagerl: the Gansch Horn.

The Raweni offers an extremely warm sound when played softly, almost like a flugelhorn. When you blow more forcefully, it responds with character and is even brighter than a piston trumpet. Its flexibility is immensely pleasing for jazz work, allowing you to create a very intimate sound even without a mute and to show your presence at any moment simply by increasing your airflow.
