And mome wraths are notoriously poor workers, preferring to dance in a circle. So I built this thing in my Home. Someday we'll have the means to edit titles and sub-titles ... ]
This isn't a concertina, but I just finished building a clavichord (stringed instrument sort of like a dulcimer) with a button keyboard of Hayden Duet layout. With all the interest in "prone" keyboards of Hayden design, I decided to build an acoustic instrument.
I got this idea back in May, worked out the design on paper and PC, and built it over the summer. Lots of woodworking experience was gained the hard way.
First photo shows the completed instrument, which is two feet deep and 18 inches wide.
Next is closeup of the keyboard. Like a Lachenal English, some keys are color coded: Red for C, black for accidentals, black bullseyes for accidentals that the player might re-tune to naturals (don't try this on your concertina ), natural wood for naturals (next time I will not mix birch and oak dowel rod stock).
Third photo is the underside of the keyboard, with its pads that push the strings against the fret board, like "hammering on" a guitar or banjo string.
Fourth photo shows the fret board under the keyboard.
I hope to bring this thing to NESI and display it along with the other oddities.
Range is from Ab below Tenor C to F an octave and a half above Middle C. Middle C is the upper red button. Hayden players can figure out the rest.
Next one I build will have a two-octave wide keyboard so you can play with both hands, a true "Duet." And maybe a 5th row of keys.
