I live in a desert climate & must run humidifiers 24/7 to keep my harps at 50%. My solution, after quite a few arrangements, is set at 3, 1gal. Humidifiers. They each have a high/low setting so depending on the day’s humidity, they are set at different speeds. During the winter w the heat on, I had to run all 3 on high. Right now, I’m doing 1 high, 2 low but I check each day & make adjustments. My dream is a climate controlled room for my harps!
I got mine through Amazon, Bell & Howell ultrasonic humidifier. It works great! Even changes colors if you want. It’s quiet and lets out a fine mist. You can adjust the level.It was not very expensive either.
I have the exact opposite! We live on the water and have way too much humidity on hot humid days and not enough in the winter. No air conditioning. I have two dehumidifiers running and can only get down to 70% from 80% in a closed bedroom. I had to sell my Lyon and Healy harp as the gut strungs string were breaking constantly.
I too need a regulated room unless someone has a suggestion?
If the gut strings are the only problem, you could exchange the pedal gut of a LH Prelude to nylgut for pedal harps as sold by Camac. Nylgut is hardly susceptible for humidity. Also, it’s rather cheap and sounds almost like pedal gut.
As you can see in the table natural Gut is the most sensitive string material to air humidity. The best choice are modern synthetic materials like Nylgut, Silkgut, Nyltech etc. and that most call Nylon. It is clear that the wood material of the harp is sensitiv to dry and extrem humid air. But between 35% and 70% rel. air humidity there should be no problems. Quick humidity changes are the greater problem.
OK. This is something I know nothing about, but we had a huge storm the other day and a tornado warning. My husband heard a loud pop and my C string just randomly broke. I went to re tune the harp and all of the strings were sharp. They had just tightened. Was that due to the storm? Not sure I could ever keep humidity stabilized as we live on an RV.
