Both of these renditions bring up for me why the use of classic Eastern European soprano voices in Verdi’s soprano music has never been a great source of listening pleasure for me. I absolutely adored Stoyanova’s Desdemona but that really isn’t like any other Verdi soprano music. She had a purity in her sound in that, that I’ve never heard her have any other time I’ve come across the voice. Quite simply both of these voices have too prominent a vibrato for me. I wouldn’t call it a wobble here, but that fact helps make the point… Something much closer to a healthy vibrato, when prominent like it is so often with these sopranos, just does nothing for me. One of the reasons I enjoyed Freni so much in this role. Also, Stoyanova has a little steel in her sound here which, of course I did not hear in Desdemona. I remember a critic a long time ago speaking about the appropriateness of eastern European type sopranos for Verdi’s music and I knew I didn’t agree. Caballe…..without the full voiced wobble on top….,Freni, Tebaldi all have warmer sounds which I prefer in this music. And in the middle of the voice, I do not hear the vibrato so prominently! I wish Stoyanova would go back to the other sound. Here, I think Yoncheva had a slightly warmer sound so I vote for her.
