The main purpose of this channel is to conserve and share authentic recordings of all kinds of traditional music, and to increase awareness and historical understanding. To support this goal, simply subscribe to this channel and explore what it has to offer. Here is another video I uploaded, which focuses on keening in Ireland and Scotland: Six authentic recordings of keening from Ireland and Scotland (1955-1965) ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-vgts7_b1JWY.html Here is what seems to be a video of a Portuguese keening song, which I would have included in this video if I found it sooner: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-96xmscvub24.html (go to 20:48)
This channel is wonderful. I hope you have it backed up in many different ways. One day these things will be gone forever. Thank you for preserving the human traditions of mourning.
Something I think might explain the similarities in types of singing across cultures is that when you're upset/crying, your voice will waver whether you want it to or not. By design, keening may mimic that and/or make it less noticeable when it happens naturally.
As Ursula K Le Geim said "It is our suffering that brings us together. It is not love. Love does not obey the mind, and turns to hate when forced. The bond that binds us is beyond choice. We are brothers. We are brothers in what we share. In pain, which each of us must suffer alone, in hunger, in poverty, in hope, we know our brotherhood. We know it, because we have had to learn it. We know that there is no help for us but from one another, that no hand will save us if we do not reach out our hand. And the hand that you reach out is empty, as mine is. You have nothing. You possess nothing. You own nothing. You are free. All you have is what you are, and what you give. "
