The tuning pins

[<- Previous] [Contents of this lecture] [Next ->]

One thing about pianos has hardly changed at all in the 268 years since the 1720 Cristofori was built: the tuning pins! They are still small metal cylinders that are driven into holes bored in a slab of wood. As all piano technicians know, tuning pins can have various problems that interfere with accurate tuning of the instrument. I am very pleased to announce - and this is the first public announcement - that I have devised a new type of tuning pin that seems to eliminate problems encountered with conventional tuning pins. My tests indicate that the new pin will make tuning easier, faster, and more accurate. Because of patent considerations, I cannot yet describe it to you but before long I hope to be able to convince piano manufacturers to use it!
