unvocal

Personally, I admire them very much, but they seem unvocal, and Italy is nothing if not vocal.

In the second-story front room at Mrs. McKee's, the barytone slept heavily, and made divers unvocal sounds.

He is a man to keep the world's tongue wagging, not too musically always; though himself of very unvocal nature.

The very word cantabile emphasizes, by antithesis, the unvocal character of the old florid style.
