Abstract
A small mass having a weight within the range of from about 50 grams to about 200 grams is utilized in an upright or grand piano to minimize or eliminate a difference in tonal amplitude and/or decay rate between at least two notes produced by playing at least two adjacent piano keys. The difference in tonal amplitude and/or decay rate may occur in a small group or region of notes produced by adjacent keys, or at those notes of adjacent keys located at certain natural scale 'breaks'. The mass is affixed to that soundboard bridge on which the note demonstrating the greatest amplitude and/or decay rate terminates vibrationally and is located adjacent the at least one string of that note.
