Human Chord [PDF ebook] 

The assertion that beautiful music shares a mysterious connection with the human soul is not a new one. For thousands of years, ever since our distant ancestors first began making pleasing sounds with whatever rudimentary implements they could lay their hands on, music has been an important part of ritual, ceremony and spiritual life. In The Human Chord, renowned master of the supernatural Algernon Blackwood takes this concept a step further – with engrossing and thought-provoking results.
