This beautiful 1829 Grand Harmonicon has a rectangular mahogany veneered case with a fold-up top and pedestal base and twenty-four mouth-blown, leaded glasses all marked with the appropriate note (except that one of the 24 glasses was replaced with a cut-off wine glass), and is accompanied by a detailed instruction book. The glasses were blown to pitch and are played by rubbing their rims with moistened fingers. The player produces the required pitches by running a wet finger around the rims of the glasses. Glasses are labeled for each note, but labels are wearing off. Each glass is etched at the bottom with the note. The case is chipped, top is cracked all the way down the middle and front knob/key is missing. Heavy pedestal on shaped plinth with paw feet is chipped and slightly wobbly. Dimensions are approximately 35" L x 21" W x 34" H.
