After Alois Doke, Linz, c. 1823
Similar to the horn, the stopped trumpet can be played one to one and a half semitones lower by using hand stopping technique. It is built in Demi-Lune form and has a tuning slide. This instrument is played with the same crooks and bits as the keyed trumpet after Alois Doke. Exception: C and Bb crooks; these must also be curved due to the curved shape of the instrument.
- Key in G (440 Hz)
- Keys are achieved through different crooks. Possible keys F, E, Eb, D, C, Bb (both 440 Hz or 430 Hz)
- Instrument in brass
