Hi Folks,
Over the course of development a number of different designs were explored for the all-bending harp. A smaller version was tested and described in my patent, but the full version was chosen for a number of reasons. Apart from overcoming the bending limitations of the small version (as on a standard diatonic, the 5 draw and 7 blow of the small version remain unable to be bent a complete semi-tone), the provision in the full version of a zero-offset enabler reed for every standard reed offers important advantages.
The current design, tuned to the regular, Marine Band tuning, permits every note to be bent two complete semi-tones, with three semi-tones for the 3-draw to complete the chromatic scale. This allows notes to be reached in a glissando from above and from below. For example, on a C harp the g2 note can be reached from the f and f# below by bending on the 6-blow. The g2 note can also be reached from the g# and a above by bending on the 6-draw. This opens up a new freedom of expression for the harmonica that goes beyond simply being able to play a chromatic scale.
Enabler reeds do more than just permit easy note bending. Their zero-offset gives them a sympathetic sensitivity that enriches the instrument's overall tone and makes it responsive to subtle variations in shaping of the airflow. In addition, the increased capacity of the reed cells obtainable in the full version adds resonance and volume not possible in the smaller version.
The production model will be simpler, slimmer and more open than earlier prototypes and will be introduced next year.
