While many musicians can wring emotion out of their instrumental weapon of choice, there’s no denying that the most emotional instrument of all is the human voice. The song’s melody and lyrics mean nothing if the voice does not connect with the listener. A notable example would be Gospel Music – the soaring voices of a church choir can melt the heart of the most hardened atheist. However, the best example belongs to The Mystery Of The Bulgarian Voices, a female choir that has mastered the art of the voice… and I don’t use the word ‘art’ lightly here. The sounds these voices make are soul-stirring and heartbreaking in equal measures.
