buzzing sound on certain keys

2019-10-17 by yinleng_c@...

Hi peeps,

I acquired a 20 year old Disklavier recently. As I played the piano, I noticed that some of the notes created this buzzing sound as I pressed onto the key, while most keys sounded clean and clear like an acoustic piano, the buzzing notes really bother me. Can someone advise what's going on?

Thanks.

Look for the obvious first: is there something on the strings?Once a small pencil ended up on my DC6A's strings under the music rack where it was difficult to see. I got an irritating buzzing.Hope it this simple,Glen Perry

I’ve found that some notes can create a resonance on the Disklavier hardware either the flap on the console or on the hardware in the underside. Try closing the flap while playing or checking the hardware underneath while someone else is playing. Might require adding a rubber washer to the mounting brackets or adding some damping elements inside the hardware.

If that doesn’t work check the interior of the piano to make sure nothing is resting in the wires. Sometimes stuff falls back there such as a pencil or pen cap...

I've already check the cabinets and strings. There's nothing inside (sparking clean and beautiful).

I'm wondering if it's the gray-scale underneath that's loosen? I haven't removed the keys to check though.
