This paper considers the characteristics of three differing styles of singing early music, as characterized by Richard Bethell [1] of the National Early Music Association, UK. In particular, the sung outputs from a postgraduate soprano who was practiced in singing all three styles are analysed along with the output from an electrolaryngograph which provides data on cycle-bycycle fundamental variation as well as vocal fold contact area. The results are compared and contrasted with those from a group of early music and opera singers analysed previously.
