Freddie Mercury’s range went from a Bass low F to a Soprano high F without using his falsetto
Although Mercury’s speaking voice naturally fell in the baritone range, he delivered most songs in the tenor range. His vocal range extended from bass low F (F2) to soprano high F (F6). He could belt up to tenor high F (F5). Biographer David Bret described his voice as “escalating within a few bars from a deep, throaty rock-growl to tender, vibrant tenor, then on to a high-pitched, perfect coloratura, pure and crystalline in the upper reaches”. Spanish soprano Montserrat Caballé, with whom Mercury recorded an album, expressed her opinion that “the difference between Freddie and almost all the other rock stars was that he was selling the voice”. She adds, “His technique was astonishing. No problem of tempo, he sung with an incisive sense of rhythm, his vocal placement was very good and he was able to glide effortlessly from a register to another. He also had a great musicality. His phrasing was subtle, delicate and sweet or energetic and slamming. He was able to find the right colouring or expressive nuance for each word.” As Queen’s career progressed, he would increasingly alter the highest notes of their songs when live, often harmonising with seconds, thirds or fifths instead. Mercury was said to have “the rawest vocal fold nodules” and claimed never to have had any formal vocal training.
