During my research and studies into microtonality and becoming familiar with the computer possibilities of alternate tunings for the acoustic horn, I worked on developing a quartertone platform for saxophone. This was more difficult than I had first thought, in that no mechanical device could be added to the body of the saxophone (i.e., a quartertone shift key), compared to adding a valve to a brass instrument. Additionally, tone control is hard to accomplish because of the variances in embouchure transitions, without bending. However, with some practice and ear training, it is possible to play note pluses and minuses in 50 cent variances.
