The short-lived Euphonicon (from Greek, "sweet-toned") was patented by John Stewart in 1841 and manufactured under his supervision. Hand-painted designs and gilded brackets soften the industrial aspect of the solid iron frame. The Macassar ebony case encloses 3 soundboxes that replace a normal sound board. Tuning is by means of screw-threaded rods reached by a long wrench. The 82 double-strung notes are sounded by soft, felted hammers; the top 23 notes lack dampers and vibrate sympathetically. Damper and una corda pedals modify the tone. Decorated on all sides, the Euphonicon can be free-standing. Delicate scrollwork and carving belie its great weight. Similar harp-pianos (so called because of the exposed strings) were popular in America around 1860.
