First I lost weight, then I lost my voice, and now I've lost Onassis. #MariaCallas

In other words, sing exactly as it's written, nothing more, nothing less, which is the phrase that I call straight jacketing, faster infinitely strictly how the composer wrote it. #MariaCallas

We serve this unique art – the music most of all. It takes a lot of worry and a lot of anguish. It was left to us as a heritage and we must carry it on against all odds – even at our own health’s cost. #MariaCallas

Even though I did not like my voice I learned to accept it and to be detached and objective. My voice is unique as is everyone’s. It is not how we sing but the uniqueness we bring – like the way we walk or talk…one’s own unique persona. #MariaCallas

It's a terrible thing to go through life thinking that you have a rock on your side when you haven't. #MariaCallas

I am not an angel and do not pretend to be. That is not one of my roles. But I am not the devil either. I am a woman and a serious artist, and I would like so to be judged. #MariaCallas

I will always be as difficult as necessary to achieve the best. #MariaCallas

Trills are necessary and they have to be well performed. Take Trovatore; Verdi and Donizetti used a lot of trills. They used them to express feelings so a trill is necessary as a technical skill for an interpreter. #MariaCallas
