tonight I had our kawai's lid open and I was playing around, nothing out of the ordinary. then in the bass about middle on down something like that, I heard and hear a click as the keys drop. please tell me this is nothing unfixable and damaging to the piano. the piano is very new so I'd be very mad if it was something that could possibly ruin it. I may be over reacting here but just worried. we have the tuner coming sometime soon I'm guessing he could look at it if it's still doing it but give me some insight!

Clicking is usually not fatal to a piano. The tech should be able to fix it. There are many things it could be. Something is probably loose. Have your tuner check the hammer rest rail, the damper stop rail, and the fit of the key frame to the key bed.

ok, so what would the difference between a technician and a tuner? :p

could a tuner do it?

A technician works on other things in the piano, besides tuning. There are a few tuners who are not technicians, and a few technicians who are not tuners, but you do not run into many these days, because it does not pay not to know how to do technicians' work, and except in shops and factories, you have to tune for your bread and butter.

what could the causes of this be? back to my original topic.
