All harps are made from european hardwoods - preferably local. Sometimes I even know the tree the wood came from. Soundboards are either Sitka or Vosges spruce (AA quality). No exotic hardwoods! The strings can be gut, nylon, or carbon, according to choice (and budget !), with strings wound with either metal or nylon for the bottom octave.

In the main I choose maple (field maple), sycomore, walnut, cherry or pearwood. The choice is largely aesthetic, but sycomore tends to have a sharp resonance, whereas walnut at the other end of the spectrum gives a softer and rounder tone...

 

Listen to Midnight 34 in walnut

Listen to Midnight 34 in oak

Listen to Crystal 30 in cherry

Many thanks to Raphaël Mateos.

At the moment I make four different sizes, based on the number of strings : 22,25,30 and 34. Harps in the more recent « Midnight » series have 22, 30 or 34 strings.
Half-tone levers are by Camac or Delacour. I am currently looking into the possibility of lighter levers with the same standard of performance.
