Here are my purely subjective (and probably worthless!) ratings on a five-point scale from 1(least) to 5(most):
| Difficulty | Complexity | Physical | Meditative |
|---|---|---|---|
| 3 | 2 | 2 | 2 |
A version is available performed by Rodrigo Leao and Vox Ensemble
A source for the music is "Ave Mundi Luminar (Sony SK 66744) {Track 1}"
