Like this, but with musicians underwater [4and20, Feb 19 2022]

Aeolian harps don't generally involve musicians, they are tuned (all strings as unisons?) and set up in a fluid flow (generally air) which excites harmonics in the strings. Which would indeed work underwater, though I'm not sure how different it would sound from a conventional airflow-driven aeolian harp.

Looking at these videos, there are interesting corollaries I hadn't thought of before. The acoustic harp sounds very weak and staccato underwater, because the mass of the water sucks the energy out of the soundboard very fast. The artist decided it was not very good and over-dubbed with a recording made in air.

The underwater music festival is kind of interesting, its not clear if they are using electric or acoustic instruments. The music there seems intended to be listened to underwater, and the comment is that the music is very treble-strong. Again it is not clear how much this is due to mal-adaption of the instruments to medium.

I think there is scope to invent genuine underwater instruments designed and adjusted for optimum acoustic performance underwater. I think an underwater pipe organ, with pressurised water fed into the pipes, could be an awesome thing.

Also since the Aeolian harp is named for Aeolus son of Hippotes who is mentioned in Odyssey and the Aeneid as the Keeper of the Winds, then this invention might be best named a Neptunian Harp or something similarly archaic and relevant

What [pocmloc] said, especially about instruments specifically for underwater.
