Here are my purely subjective (and probably worthless!) ratings on a five-point scale from 1(least) to 5(most):
| Difficulty | Complexity | Physical | Meditative |
|---|---|---|---|
| 2 | 2 | 1 | 5 |
A version is available performed by Findhorn Community Singers
A source for the music is "Cantiones Sacrae Vol 2 "
