Kristin Borgehed's paper was recently presented at the Nordic Network for Vocal Folk Music Research Conference.
Kristin's paper investigated how melodic structures in singing are flexible, and shaped by things such as context, pronunciation, volume, and gender.
This conference was held in Stockholm at the Royal College of Music
