The following are quotes from people who have heard music during a N.D.E.

"And the whole garden was singing. The flowers, grass, trees, and other plants filled this place with glorious tones and rhythms and melodies"

"And then I heard the MUSIC. It was a tone so sublimely perfect that remembering it still brings me to tears. I knew then, and know now, that I was hearing the symphony of angels, the song of the universe, what some have called the Music of the Spheres. All thoughts melted in its melody and everything else ceased to be of any importance. I closed my eyes and began to dance, moving to the resonant vibration that coursed through my essence. The melody seemed to issue from a single point and was composed of one verse, a song whose mystical tone my entire being knew and sang. I bathed in its melody as utter joy filled my being, and as the sound washed over my spirit, I felt all confusion purged from my consciousness..."

 " This time we were audience to a choir of angels singing. Angels were totally outside my reality at the time, yet somehow I knew these beautiful beings to be angelic. They sang the most lovely and extraordinary music I had ever heard. They were identical, each equally beautiful. "

Pete also descibes it in the 3rd part of his story 'The Boy who heard music'

‘I heard it in the air, between the stars and the trees.’

‘It was sometimes like singing, sometimes like grand orchestras playing Beethoven’s symphonies. It was always very beautiful.’
