How D.O. uses that range
Warm and rounded even at speaking pitch, this voice sits low for a tenor and gains its color from a relaxed jaw and tall vowels. D.O. ornaments melodies with short, precise runs, placing each passing note rather than smearing. Vibrato arrives late on held tones, narrow and calm. Imitators tend to breathe shallowly and chase his darkness by depressing the larynx; the actual sound is forward, unforced, and conversational up through the mid-fourth octave.
