No reliable evidence shows that Freddie Mercury’s prominent teeth gave him extra vocal range or made his voice more powerful. A 2016 acoustic study instead documented distinctive qualities in recordings of his voice, including a 37-semitone singing range, rapid vibrato and sounds consistent with subharmonic phonation. The idea that his teeth created his range was popularized by Bohemian Rhapsody; it is dramatized dialogue, not a finding of the study.
What the acoustic study found in Mercury’s voice
In a peer-reviewed 2016 study, Christian Herbst and colleagues examined recordings of Mercury rather than testing him in a laboratory. Their work offers measurable descriptions of the voice captured in those recordings, but it cannot establish that a particular feature of his anatomy caused them.
Singing range: 37 semitones
The researchers estimated Mercury’s singing range at 37 semitones, from F#2 (about 92.2 Hz) to G5 (about 784 Hz). They did not consider reported higher phonations, including evidence at 1,347 Hz, reliable enough to include. The range is an estimate from the available recordings, not a claim that every note was part of his typical performance.
Speaking voice: a baritone-typical median
Analysis of six interviews found a median speaking fundamental frequency of 117.3 Hz, a value typically found for a baritone voice. That describes sampled speech; it does not define the range or character of Mercury’s singing voice. The paper’s abstract reports this result in the University of Vienna’s study record.

Vibrato and unusual vocal effects
The team analyzed 240 sustained notes from 21 a-cappella recordings. They measured a mean vibrato modulation rate of 7.0 Hz and reported evidence consistent with the irregular vibrato listeners may notice in Mercury’s singing. Their analysis also found evidence consistent with subharmonic phonation and vibration of the ventricular folds. Because these observations came from retrospective recordings, they support those interpretations without proving every physiological detail of how Mercury produced each sound.
Co-author Christian Herbst described the project as “an attempt to gain some objective insights into his singing style, using rigorous scientific methods rather than subjective imagery” in a 2016 Live Science interview.

What his teeth do—and do not—explain
Mercury was widely associated with prominent teeth, and Bohemian Rhapsody helped popularize the idea that they gave him more vocal range. But the study measured acoustic features in recordings; it did not investigate Mercury’s dental anatomy or test a tooth-to-voice effect. None of its results shows that his teeth made his voice more powerful, expanded his range or gave it a special quality.
In a Fresh Air interview about preparing for the film, actor Rami Malek described Mercury as having four extra upper teeth and discussed the prosthetics used for the role. That is Malek’s account, not an independent clinical record. The film’s dialogue linking extra mouth space to greater range should likewise be understood as dramatization, not scientific evidence.

The available evidence does not establish a clinical dental diagnosis, an unusually large mouth cavity, or a confirmed reason Mercury may or may not have sought dental treatment. Those claims should not be treated as explanations for his voice.

The recordings reveal a combination of traits—an estimated broad singing range, rapid vibrato, and vocal effects consistent with subharmonic phonation—that helps describe what listeners hear. The study does not isolate a single cause or reduce Mercury’s sound to one anatomical feature. Queen’s official biography calls his voice “immediately recognisable” and his range “remarkable,” a band-approved characterization rather than a scientific assessment: Queen’s Freddie Mercury biography.
