Examples:

"The interplay of warring voices informs the thesis of Pan’s project. The abstract structure, at least compared to a traditional opera, piercingly emphasizes the beauty of its arrangements. Across the seamless span of 'A Found Lament' and 'A Tender Accent,' swooning sighs and orotund [mezzo-soprano](https://www.merriam-webster.com/dictionary/mezzo-soprano) are backed by an almost melodic drone, and high-pitched voices cry out, '害怕! (Fear!),' to protest the [minatory](https://www.merriam-webster.com/dictionary/minatory) wall of mechanical sound encroaching on them." — Zhenzhen Yu, Pitchfork, 22 Jan. 2022

Did you know?

An experiment: first breathe in deeply, then try to sing the strongest, lowest note that you can, at the utmost floor of your [register](https://www.merriam-webster.com/dictionary/register). How lovely. Now, what vowel did you sing for your one-syllable song? We’ll bet you a skillet full of bacon it was [o](https://www.merriam-webster.com/dictionary/o). Why? Shaping one’s mouth into an o-shape is pretty much a surefire way to produce an orotund or resonant sound, that is, one that is full, strong, and loud. Try the same exercise with a long e sound, as in sleep, and see (or hear) what we mean. Orotund comes from the Latin phrase ore rotundo, literally meaning "with round mouth." It was adopted into English in the late 18th century to describe the strength of one’s vocal delivery but has since picked up an additional sense of "[pompous]( https://www.merriam-webster.com/dictionary/pompous )" or "[bombastic](https://www.merriam-webster.com/dictionary/bombastic)" to describe inflated speech that may be full of sound and fury, yet signifies nothing.
