Bass trumpet in Bb
French: trompette basse
Italian: tromba bassa
In today’s orchestral practice the bass trumpet is played by a trombonist because the instrument’s mouthpiece is similar in size to the trombone’s.
The above shown bass trumpet is unusual in that it has three valves, like the original instrument made in Wagner’s day, instead of four as on the modern bass trumpet.
