A Voice Like No Other

Freddie Mercury (born Farrokh Bulsara, 1946-1991) had one of the most remarkable voices in recorded music. A study in Logopedics Phoniatrics Vocology analyzed his singing and found that his vibrato was faster and more irregular than the steady vibrato of trained opera singers — one reason his voice sounded so distinctly human and alive.

Mercury is often credited with an enormous range, but the 2016 acoustic study usually cited for his voice did not confirm the four-octave claim. It found his range was not unusually broad for a healthy adult singer, while highlighting something more distinctive: his unusually fast, irregular vibrato, baritone speaking voice, and exceptional control as he sang in a tenor-like range.

Range alone does not explain Mercury. His voice combined operatic power with rock rawness, and he could switch between them within a single phrase.
