Haunting melody - famous song - slow quiet ballad
I was positive that the tune in my head is very famous, but could not tell the name of the track, or the author. So I recorded myself playing the intro of the music and uploaded it to youtube, hoping someone will recognize it and provide information about it.
I used Shazam and SoundHound and other music identifications services, but nothing turned up. It is slow, quiet, mind easing classical music, and I have been looking for it for 30 years.
@JohnnyBones the suggested track has nothing to do with the track I'm looking for. But thanks anyway.
