Just a quick note to congratulate you on your marvellous magnum opus "Vox Arcana. Teoria and pratica della voce". It is an ambitious work, conceived on a grand scale and extremely well executed. A wonderful achievement by any standards, and I have enjoyed reading it very much. In fact, I enjoyed it so much that I translated several pages into English so that I might cite some passages in my own books: "A History of Vocal Pedagogy: intuition and Science", and "Vocal Science for Elite Singers". Once more, Congratulations and best wishes, and thank you for serving our art so extremely well.
