The "vioară cu goarnă" is the Romanian term for the Stroh violin, which is a type of stringed musical instrument that was invented in the late 19th century.

The Stroh violin is similar to a regular violin, but it uses a metal horn instead of a wooden sound box to amplify the sound of the strings. The horn is often made of brass or other metal materials, and it is attached to the body of the violin, extending out from the top of the instrument.
