In certain areas of her range her voice also possessed a guttural quality. This would occur in the most delicate and troublesome areas of a soprano's voice—for instance where the lower and middle registers merge, between G and A. I would go so far as to say that here her voice had such resonances as to make one think at times of a ventriloquist ... or else the voice could sound as though it were resonating in a rubber tube. There was another troublesome spot ... between the middle and upper registers. Here, too, around the treble F and G, there was often something in the sound itself which was not quite right, as though the voice were not functioning properly.
