It was a large gilded harp that sat in the center of a merry-go-round, playing the oom-pah-pah waltzes as the whole thing turned around it. An elderly woman with blonded hair and an old stole sat and played, oblivious to all as they whirled about her. When I came back to see it again, it was all gone, left for another town.
The Hohner Harp-Harp
This wood and chrome harp was made so you could blow through the sound-holes while playing and play the harp both as a harp and a harmonica at the same time.
I never saw this one, but I heard about it, a harp on wheels for the wheelchair-bound harpist. It had straps to attach it to the chair, so it wouldn’t roll away. The wheels were attached next to the rear feet.
