Harmonicor
Not on view
Although the psallmelodicon, symphonion, and mouth organ initially failed and fell into disuse, they enjoyed a comeback as children's instruments a few decades later. Among such children's instruments is this variant in the shape of a Roman cornu. Its predecessor is the psallmelodicon, or the harmonicor of Louis Jules Jaulin in Paris (1859-61). The musically active part is the center tube with twenty-four keys, under which twin reeds respond to pressure and suction.
