I have just begun playing the harp, and have a brand new Camac Excalibur which I bought in June this year (3 months ago). I am currently unable to get a lesson with any teachers nearby so cannot ask a teacher or harp player for advice on a problem I am experiencing with one of the levers.
The lever in question is on the E4 string. The problem I have is that this lever sounds the string whilst being engaged. Having watched closely, I can see that as the lever is pushed up, the string seems to knock the edge of the little groove it rests in when the lever is fully engaged. This produces a sound from the string. When the lever is fully engaged, the string rests properly in the groove. It seems as if the whole string is no longer connected between the peg and the lever at the correct angle- the string is slightly to the left of where it should be in order to hit the groove at the right angle.
I have been playing on this harp every day for the past few months and never experienced this issue. The only thing that changed is that this evening I finally got an electronic tuner and was able to tune it properly. When I used my electronic tuner I realised that the strings were all flat by a whole tone so I gave them all a good tightening. It was after this that the problem with the lever occurred, but I cannot see why this would be! None of the other levers have been affected.
I am sorry if this is hard to follow, but I would really appreciate some advice from a more experienced harpist or harp maker!
