CORRECT PITCH
The sound of Thill's voice in other uploads of this footage was bothering me. The upper pitches seemed a tad shrill. I consulted the score and discovered that the other uploads were pitched a half step too high.
I've restored the true pitch, and Thill's voice comes across with more authority and depth, and we can appreciate the beauty of the voice that was cultivated in the one, true Italian school via the instruction of Fernando De Lucia.

This channel is primarily about vocal emission-aural examples of basically correct singing, correct impostazione-chiaroscuro, vowel clarity, firm and centered pitch, correct vibrato action, absence of throatiness or thickness, sounds free from constriction and from the acoustic noise that accompanies it-with occasional video examples that demonstrate what the body, face, mouth, jaw, and tongue look like when used with correct impostazione-the vocal emission of the one and only Italian school.
Caveat: I'm biased in favor of baritones and baritone literature, but if you want to learn about and listen to all the greatest singers in the old-school tradition, explore this spreadsheet (voice parts are separated by tabs): bit.ly/2W4qmE3
