I would like to see instrumentation in place to measure the pitch, I didn't see hydrophones, only the sound of the violin that escaped the surface of the water, at least that's what it seemed like. I would like to see hydrophones record the sound and to demonstrate the actual pitch as perceived underwater. The pitch as heard in the video was the same as the sound of it underwater which pretty much proves it was sound recorded above the surface where you would hear normal air frequencies, the pitch should change a lot because of the increased speed of sound underwater. These were just kids trying an experiment. I would like to see a real scientific project with real instrumentation. Still interesting though, also would like to have a translation from whatever language that was, Swedish? Dutch? At the very least, it proved a violin can produce sound underwater.

I would like to see this girl play underwater:

I don't think so.
I think the viscosity and density of the medium in which the violin is played has an important role how the sounds is generated.

The sound will not resemble the acoustical sound of a violin. Obviously, the resonator box will not have a hand in the sound generation. The sound produced in the air by a violin is complex, with undertones and overtones surrounding the fundamental note. That is why a guitar sounds different from a cello - they are similar size and pitch but the guitar is producing much more of the fundamental tone without the overtones and undertones.
What would be heard from a violin being played under water would be sound that is much more fundamental. It would be the same as if one were using a transducer pickup on the violin bridge or playing a mute violin. The pitch, however, would not be changed. Water does not alter sound in and of itself. It is a far better conductor of sound than air is, though.

The reason it sounds like it does is because it is a percussive instrument, anything that plucks strings from mandolin to guitar to harpsichord are all percussive and anything bowed is more continuous toned obviously both have overtones (harmonics) and such but the main difference in plucked instruments is the percussive effect, a tone that starts and stops more abruptly than the cello/violin bowed instruments.
