Monsterrat Caballé is a world-famous tempestuous Diva, highly-regarded for her shimmering, lovely pianissimo. And while she might sing a high note piano when Verdi actually asked for it to be mezzo-forte, or perhaps even hold said high note for a bit longer than is asked, she does this in such a beautiful way that one can only imagine Verdi was mistaken, and the Diva is, in fact, the correct party. She is a particularly winning Soprano soloist in Verdi's Requiem. A recent DVD release of a documentary showing rehearsals at La Scala for performances of the Verdi Requiem, reveal a true Caballé moment: in rehearsal, the pianist plays her first note-- several times-- and each time she misses it, falling into a gale of giggles, which quickly have the chorus and conductor laughing, too.
