What's resonating? If the slats themselves are resonating, spacing them differently won't help much. Then again, if it is the slats would a horizontal brace run

  Good point, it could be that they are vibrating like reeds. Bracing could help in that case. or could they attach weights to each one to change the resonant behavior ? It would be interesting to get a high speed video of one to see.

  Dampers are probably only solution that doesn't involve rebuilding it. I haven't seen a great photo, but one of the videos seems to show the rails are square tubing...so could be vortex shedding? Running a brace might not be a bad idea, but i could imagine that it might just double the octave, and make it a bit quieter

    if damping weight work I could see a crowd sourced solution, a lot of people in the area could get some gorilla glue and a bucket of pebble and glue them on the slats.

    Update: Just saw the video from the manufacturer, and it's not tubing like I thought I saw, but just flat stock steel. No wonder they're singing
