Menu:
Current Design Status
Currently Designing - Prototype 6
45 strings; fully chromatic throughout bass range and melody range.
Tapered keyboard optimizes key size and keyboard width at front and rear ends.
Distinct pivot points for white and black keys; optimises keylever ratio throughout the keyboard and improves keyboard touch and feel.
Bespoke pulleys for each section of the lower action.
Optimize string length (longer bass strings).
Radiused top plate with bass lobe and improved bridging.
Integrated 3d printing techniques.
Currently Playing - Prototype 5
This 42 string harp body was commissioned from luthier Alec Anness. The design optimizes the string surface allowing improved pitch range to high DIt; is fully chromatic in the melody range which is identical to prototype 6. There are 9 bass strings the lowest corresponding to a guitar low E. The sound is warm and robust and has allowed significant development of technique (abandoning all picks save thumb pick).
I have built the upper action with a similar design intent as for prototype 3, with various improvements.
Two integrated small daiphragm condenser microphones provide sound reinforcement for louder ensemble work such as the Adelphi Contemporary Music Ensemble (below, taken from a concert in Peel Hall, Salford 2014)
