Learning to sing the psalms. For nearly 1,500 years, Gregorian chant was the universal language of Christian monasticism and psalmody. But after 1961, Gregorian chant was essentially shelved in favor of a move to vernacular languages as a result of Vatican II, the Great Papal Council. We've been in a period of great transition as monastic houses have worked to find and replace the ancient Gregorian chant tradition with something else.
Many people think that Gregorian chant and the Christian chant tradition are one and the same.
Jesus Christ didn't sing Gregorian chants, neither did the Desert Fathers nor countless others of the most powerful and profound witnesses to the Christian spiritual tradition. So, there must be something else, some deeper wisdom at the root of Christian psalmody. In Christian chant, neither the vibration itself, nor the music is sacred. Certainly Christian chant makes use of vibration as all chant does. But it is not primarily about sacred vibration.
