You came to mind when I was looking up more about an instrument I've heard only in the movie Amadeus.
Bubak And Hungaricus is early 18th Century gypsy music which was arranged by Jaroslav Krček and included on the Amadeus soundtrack. The composer is unknown, but it’s a fun old Central European folk musical piece which seems to have been turned into a court dance tune over time. These folk dances which was performed at the palace as a curtain raiser to Mozart’s music show how classical composers constantly drew from the folk music that was all around them.
In the feudal courts of Europe, the usual instruments of strings, cornets, and harpsichords were often joined by folk instruments, like a bagpipe made from a sheep’s bladder. The ensemble heard here includes an ancient recorder-like flute, and a curious single-string double bass with a penetrating drone, the tromba marina, so named because it was used as a foghorn on ships.
