UN CANTO LIBERO

From "The Secret of Bel Canto", an article by Matteo Glinsky, the noted musicologist:

Le teorie pedagogiche di Lodovico Szamosi a prescindere dal loro valore empirico, ci rivelano forse veramente quel segreto del bel canto italiano che molti oggi considerano irrevocalmente perduto.

Translation
Lodovico Szamosi's pedagogic theories -- apart from their practical value -- have perhaps finally illuminated for us those secrets of the Italian bel canto that many until now believed to be irretrievably lost.
