I am going to ask for your expertise again, and thank you very much in advance.
I left my 22-string lap harp in Asia, because harps are rare in Taiwan and my nine-year-old cousin thought this instrument was very interesting, and bought myself a used 34-string Aoyama lever harp today! The previous owner acquired it in 1995, used it for about 10 years, and then left it in a bag for the next eleven years. At the time I bought it, it was missing two strings, the lowest B and highest B; it was somewhat dusty; and it was not in tune. I mostly wanted to use it while I look for a harp whose sound I can love.
I missed a few cracks when I bought it, or the cracks appeared after I tuned the strings. There are a few cracks on the soundbox. All of them are vertical and none are on the soundboard. There are only two cracks on the inside (#2 and #3) on the non-levered side of the harp and these cracks are not visible from the outside. #2 is near the bottom of the soundbox and #3 is higher up. The other cracks are only on the outside of the sound box and #5 has gone halfway through the wood, when I look at the crack’s end(s) on the edges of the soundbox holes. #1 is near the bottom, on the side of the harp without levers. #5 stretches from the second to the third soundbox hole on the harp.
Is this harp okay to use, in this case meaning that I should not be worried about the harp spontaneously exploding from the string pressure? Are these cracks important to fix right away, and are they worth fixing? On a point more of curiosity, what might be a likely cause for these cracks?
Also, how do I find a list of harp technicians? I keep getting lists of harp teachers or websites of harp makers (who do not live within 100 miles of me) when I try to search for a list online. I could wait until next year’s Somerset Harp Festival in NJ, I know, but I think I might need to get this harp to a technician sooner.
