Piero Cappuccilli Il Trovatore Verdi tuning

Piero Cappuccilli (baritone) demonstrates the difference between the scientific musical pitch of A432 (the socalled Verdi tuning ) and the higher, unnatural pitch of A440. In this example, he sings a part of Il balen del suo sorriso from Il Trovatore by Giuseppe Verdi. In this aria, the baritone is forced by high tuning to incorrectly pass the register before the Enatural, as a result of the effort on his vocal cords. Cappuccilli gives this example twice, first singing with the piano tuned to A43
