Piano tuning retention system

A method of installing a piano tuning retention system in a piano, the method comprising:

• fitting a lower longitudinal end of a first bushing onto a polygonal end of a first piano tuning pin of the piano, the lower longitudinal end defining a polygonal interior for mating with the polygonal end of the first piano tuning pin;
• placing a first sleeve over the first bushing, the first sleeve having an inner diameter greater than an outer diameter of the first bushing and having an upper longitudinal end with an inward radial extension that defines a reduced inner diameter less than the outer diameter of the first bushing;
• fitting a lower longitudinal end of a second bushing onto a polygonal end of a second piano tuning pin of the piano, the lower longitudinal end defining a polygonal interior for mating with the polygonal end of the second piano tuning pin;
• placing a second sleeve over the second bushing, the second sleeve having an inner diameter greater than an outer diameter of the second bushing and having an upper longitudinal end with an inward radial extension that defines a reduced inner diameter less than the outer diameter of the second bushing;
• placing a bridge on the upper longitudinal ends of the first and second sleeves;
• connecting a first fastener to an upper longitudinal end of the first bushing with the bridge and the inward radial extension of the first sleeve therebetween, causing a circumferentially extending catch defined by a lower longitudinal end of the first sleeve to engage with a piano string held by the first piano tuning pin;
• and
• connecting a second fastener to an upper longitudinal end of the second bushing with the bridge and the inward radial extension of the second sleeve therebetween, causing a circumferentially extending catch defined by a lower longitudinal end of the second sleeve to engage with a piano string held by the second piano tuning pin.

A piano tuning retention system for impeding rotation of a plurality of piano tuning pins of a piano, the system comprising:

• a bridge that spans the plurality of piano tuning pins;
• a first assembly for engagement with a first piano tuning pin of the plurality of piano tuning pins, the first assembly including:
• a first bushing fitted on the first piano tuning pin, the first bushing having an upper longitudinal end and a lower longitudinal end that defines a polygonal interior for mating with a polygonal end of the first piano tuning pin;
• a first sleeve placed over the first bushing, the first sleeve having an inner diameter greater than an outer diameter of the first bushing and having an upper longitudinal end with an inward radial extension that defines a reduced inner diameter less than the outer diameter of the first bushing, the first sleeve further having a lower longitudinal end that defines a catch extending in a circumferential direction of the first sleeve for engagement with a piano string held by the first piano tuning pin;
• and
• a first fastener attached to the upper longitudinal end of the first bushing with the bridge and the inward radial extension of the first sleeve therebetween;
• and
• a second assembly for engagement with a second piano tuning pin of the plurality of piano tuning pins, the second assembly including:
• a second bushing fitted on the second piano tuning pin, the second bushing having an upper longitudinal end and a lower longitudinal end that defines a polygonal interior for mating with a polygonal end of the second piano tuning pin;
• a second sleeve placed over the second bushing, the second sleeve having an inner diameter greater than an outer diameter of the second bushing and having an upper longitudinal end with an inward radial extension that defines a reduced inner diameter less than the outer diameter of the second bushing, the second sleeve further having a lower longitudinal end that defines a catch extending in a circumferential direction of the second sleeve for engagement with a piano string held by the second piano tuning pin;
• and
• a second fastener attached to the upper longitudinal end of the second bushing with the bridge and the inward radial extension of the second sleeve therebetween.
