Good evening everyone,
Found this today on one of our D’s. It’s at the highest treble strut. Here is some history on this piano:
Built in 1976
Piano has been restrung a couple times but harp has never been removed.
Pitch has always remained consistent as UNC- Greensboro music building has an extremely reliable climate control system.
Piano has been moved several times but always by same professional piano moving company.
No pitch change in area around cracked area.
I tune this instrument every week.
In 40 years of servicing and restoring pianos I have never encountered this on any model Steinway.
Thoughts?
