if you believe, as i do, that listening to the roots of the music and absorbing styles is important in formimg ones own style, be it singing or instrumental music, then my criticisms of the style of Peter Pears singing Waly Waly for example, wouldbe that is over stated over and dramatic,because his roots are closer to the operatic style.
it is not just about stylistic use of ornamentation in the music
in Art music is stipulated and written down whether you should use a mordant or a trilll or something else, that is not the case in solo unaccompanied singing of tradtional music
