The science
under the method
A doctoral thesis and five peer-reviewed papers.
Daniel Zangger Borch was the first Swedish voice pedagogue to study the rock, pop and soul voice scientifically, working with Professor Johan Sundberg at KTH Royal Institute of Technology in Stockholm. The work has been cited more than 250 times.

The thesis
Sång inom populärmusikgenrer
Singing in popular music genres — artistic, physiological and pedagogical aspects. Doctoral thesis, Luleå University of Technology, School of Music in Piteå, 2008.
The thesis draws together five separate works: three articles in Logopedics Phoniatrics Vocology, the book Stora Sångguiden, and a recording. It was the first Swedish doctoral work to treat contemporary singing as something a laboratory can say useful things about.
