I took my 22-string lap harp, a Stoney End Brittany, with me to Taiwan on September 5th by plane. Carry-on, of course, as I knew it would fit in the overheads.
A few days after arriving, I noticed black spots all over the harp. I have attached a few pictures, but these spots can be found literally on every side of the harp. I thought that perhaps they had always been there at first, but I feel like they are definitely more than there could have been before for me to not notice them, because I do like to admire my instruments by looking at them fairly often.
Perhaps they were there before but smaller, and something made them bigger. Is this something to do with the high humidity in Taiwan? Is it that I picked up some sort of wood-eating insect while travelling? If it is humidity, will it stop once I bring it back to the US?
I would really appreciate any help in understanding what happened.
Thank you ahead of time.
