Chinese man sings across six octaves...

.... and no, he's not a eunuch or anything. 52 year old Chinese music teacher Li Wenxing (李文兴) is now practicing to reach six octaves plus one minor triad to break the Guinness record for world's widest vocal range, currently held by American Tim Storms. Just for comparison, the average person sings 1-2 octaves, professional singers with extensive training can sing about 3 octaves unstrained, and Mariah Carey is able to reach 5 octaves.
