Overview
A fascinating hybrid stringed instrument known as a 'fretless zither,' featuring a distinctive double-bout body and a series of chord groups. This model was designed to be played by anyone, regardless of musical training, using a numbered system of notation.
Story
In the 1890s, door-to-door salesmen sold these as the 'future of home music.' They promised that even a novice could play like a pro in minutes. It turned Victorian parlors into DIY concert halls long before the radio existed.
Maker / Origin
The Phonoharp Company was founded in 1891 and became a titan of the 'parlor instrument' craze. They eventually merged with their rival to form the Oscar Schmidt International company, the legendary makers of the Autoharp. Their goal was to democratize music for the American middle class.
Condition & Value
The instrument shows significant dust and age-related oxidation on the strings. The wood finish appears largely intact, though the tension from the strings may have caused slight bowing over 130 years. Missing strings or a cracked soundboard would reduce value by 50%.
