"Presley had a unique voice, with a quite tonal perspective. He could belt tenor range notes and his vibrato is understated, especially in ballads. His pitch accuracy is also hidden, and that is one of his most outstanding qualities. Dynamically, he knew how to sing each song, leaning in, and making each performance even more personal than the writer of the song had meant or had wanted it to. The best examplle of his vocal ability is the totality of what he sang, namely in the sense that every song he sang sounded as good as it did. His natural vibrato covered several semi tones, which made his singing even more dramatic. He had the ability to change his voice to suit a song, rather than the other way around. Over the years, he added that smokey quality and the raspiness in his voice was all natural, but it was always a voice that rested in between the notes. He is one of the most heard singers of all time, which means that ultimately, his voice, at his best, can not be categorized because as npointed out earlier, it will always remain one that rests in between the notes, no matter who listens to it."
