​Welcome to One Spirit Music

The purpose of ONE SPIRIT MUSIC is to support, promote and facilitate peace and compassion based on shared values of love, tolerance and inclusion for all human beings through the creation of Interfaith liturgical music and events.

As music can bring people together, we offer an Interfaith musical event called ONE SPIRIT, ONE VOICE at churches and synagogues, featuring contemporary prayer-songs based on ancient texts from the Abrahamic faith traditions such as Hallel Psalms: Give Thanks to God!, The Lord’s Prayer Experience: An Interfaith Journey into Song & Spirit, and Love Your Neighbor — It’s the Golden Rule.

Join us on an uplifting musical journey as we sing these ancient prayers and pray the music in new ways relevant today for people of all faiths — and turn our voices into a shared vessel for summoning the One Spirit.

Our music is available to be shared digitally with your community. For more information, contact Yosef@onespiritfoundation.org.

Hallel Psalms 6-Song Composition

The Lord’s Prayer Experience is an inspiring musical journey based on an early ancient Hebrew text of the prayer.

Love Your Neighbor includes a children’s chorus asking to treat others and the planet as you’d like to be treated.
