My whistles are crafted in metal (aluminium and brass) mainly, using a conventional mill and lathe, while some parts are CNC machined.
For some models a carbon fiber body is proposed. It has a different look and feel, reminding of ebony wood – yet much tougher and maintenance-free.
All my whistles are tunable, with a brass tuning slide. Fipple blocks are made out of food-grade technical plastic (Delrin).
I do not copy any existing model, and my bore and tonehole templates are computed by means of a homemade computer program.
Based on experimental and theoretical data on the acoustic impedance of pipes, toneholes and radiation ends, I have developed a acoustical simulation program for optimizing the placement of resonance modes within the physical and ergonomical constraints of the instrument. This program is written in Scilab and is suitable for the design of flutes in all keys and sizes.
Tuning and voicing
I have produced many prototypes and different models which were tested by several expert or professional musicians (to whom I express my gratitude).
Shape parameters of the fipple (canal size, block bevel, labium ramp angle, window size, etc) have been carefully chosen to provide a clear, somewhat powerful sound, yet with a rich timbre. Great care is taken regarding pitch accuracy and tone balance between registers.The curved windway design and block material reduce clogging effects due to breath condensation. Toneholes are individually undercut and bevelled slightly on the exterior. An insert is placed in the bore to optimize pitch accuracy of the high notes.
All of my instruments are assembled, tuned and tested by myself.
