In Queen, the vocal harmonies are made a hundred percent by Freddie, Brian and Roger. There are very few songs in which the choirs are made only by Brian and Roger (except for the songs composed after Freddie’s death); on the other hand, Queen composed many songs where Freddie does all the choirs on his own.

    The three member singers of Queen (since John Deacon, the bassist, has declared that he did not participate in the choirs since he could not sing a single note) possessed light enough pitches, and tenor voices: the three were used to singing over the C4, although we can note that Brian did it with certain difficulty, since he carried his chest voice and head voice to the maximum in all the high tones, a situation which might have cost him the loss of his voice had he been the leader voice of Queen.

    Freddie has a pure sharp voice. Roger has a rougher pitch, a ripping voice, and Brian sings with a tone that stumps it all. Brian has a very similar pitch to that of Paul McCartney. If we listen to the song '39' from A Night At The Opera, we can barely notice the difference. They do not only have a similar pitch, but their ranges are practically equal, with the difference that Brian is not used to singing in falsetto, and Paul has the tendency of forcing the voice to get to the high notes (just as Freddie did in his moment), or of simply passing to falsetto (although he favors the latter).

    Roger Taylor has greater facility for the high tones, he has a great falsetto voice. He is the one that produces the classical screams in the choirs of Queen. Roger is the one that reaches the tones over the F5, the High F, more easily. In the culminating part of the operatic section in 'Bohemian Rhapsody', Roger produces the famous Bb5 in the end.

    Brian May, on the other hand, has greater facility for the low tones than for the high ones; but when it comes to speaking, he has the lightest pitch of the four members of Queen. He does not possess a great vocal technique (though he does have a great voice) and he forces the vocal cords a great deal to reach the high notes. Along with Freddie, he performs the lowest notes in the most complex harmonies ('The Fairy Feller' s Master - Stroke', 'Bohemian Rhapsody', 'Somebody To Love', 'The March Of The Black Queen').

    The unique and unrepeatable Freddie Mercury, is the only member of Queen that participates in all the choirs, since he has some very penetrating highs, and reaches good lows. He sings the low tones in 'Somebody To Love', for example.
