Ralph David Hill
Ralph David Hill was a Composer, Music historian, Psycho-acoustician, Music software and hardware developer, and was enthusiastic about the Natural Harmonic Series and the effects of musical tunings on human beings.
Dave developed several generations of computer based voice and sound analysis programs, with hardware of his own design and construction, as well as voice and instrument synthesis, beginning in the 1970's.
Included here is a rendition of Ivor Darreg's Prelude in D Major, in 7 limit just intonation.
In addition to his work with the Harmonic Series and Extended Just Intonation, he explored the Meantone tuning, as used on 19th century pianos, and recorded some examples, which are presented here.
