Disklavier

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

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.
