I think that meditative music must be based on improvisation, on the mood of the moment that you can't regain anymore. On recording, the first take is to be chosen.

It shouldn't be necessarily relaxing, so that none may confound meditative music and new age music.

It may be hypnotic, but it doesn't necessarily induce a kind of trance.

To enjoy this music you have to get rid of the categories of beautiful and ugly. More often than not, it's a music of a school, or an esoteric teaching and as such it has to be heard.

You may dance along with that music or be still, as you like.

This kind of music has been practised for a long time, and it will always exist.
