Description
Tone, tension, and time are examined together in this specialized computational tool, created for piano technicians shaping hammer felt by hand, concert tuners managing stretched octaves in changing humidity, restorers matching historic wire scaling, and acousticians studying the complex behavior of large grand pianos. It follows how felt compresses with repeated voicing, how steel wire slowly elongates under constant load, how the soundboard crown shifts as seasons change, and how partials finally align within unequal temperament. These steady insights help reveal the moment when a piano holds its voice with confidence or begins to drift away from harmony.
