I got my first lever harp in May and I’ve been teaching myself how to play, but about two months ago I was practicing my harp and I noticed that in one of the octaves some of the strings were making a weird buzzing noise. I’d assumed it was because of the temperture change because the room I’d been playing in had been warm and then the air conditioning had been turned on but once i had moved it to a constant temperture room even after a few days it was still making the noise. For a while i ignored it and just tryed to play in a diffrent octave, but then instead of a few strings it was the whole octave. When i played the string gently, it was quiet but I could still hear it buzzing. When i played the same string loudly I could actualy hear the buzzing and could barely hear the note. Has anyone else ever expierenced this and where you able to fix it?
