My interests are singing voice and the organ and I created the Vocal Tract Organ as a novel musical instrument and it is still in development. I am interested in tuning and especially non-equal temperament (all intervals are out of tune in equal temperament except the octave). I am currently working with the alaryngeal choir (singers have had their larynxes removed sue to throat cancer) with a view to pproviding them with vocal tract organs to perform with.
