I just got a new harp with 40 gut strings. (L&H Prelude 40) I can keep my room with humidity of 38% with two humidifiers with my best effort in Chicago. Still, within a few days, two strings were already broken. One was while tuning, and the other one was out of blue. How many strings do you usually lose in a year? I wonder if it’s a problem of not having enough humidity. I would like to hear about your experiences. Thank you!
I would call the shop and tell them which two strings broke and where exactly they broke: near the grommets, or the tuning pins or bridge pins, or somewhere in the middle? Did you see them fray a bit before they snapped?
It’s kind of to be expected that strings that break in the first few weeks (I know one shop that even uses a period of three months!) after purchase of a new harp be replaced for free.
There may be small burrs that cut through the string. You can remedy this with abrasive chord (sold by harp shops).
I use a Venta Airwasher to keep the humidity in the room between 40 and 60%. If you are new to using humidifiers, the room may need several days to slowly reach that level, as the still very dry, but moist absorbing elements in the room will absorb some of the moist.
