Variations on the AIR signature tune

The AIR signature tune is usually attributed to Walter Kaufmann and is now confirmed by Zubin Mehta (see the interview from 30 minutes onwards). Apparently, it is based on raga Shivaranjani, possibly with some east European influences. It is recently discussed in tajmahalfoxtrot. In a follow-up Amit Chaudhuri Responds to the Kaufmann story “Now the tune makes a lot of sense, and why, when I would hear East European buskers play in Berlin, I would often want to have them play with me in my version of AIR. The subterranean, tremulous East European, slightly folksy sound of the theme now becomes clearer to my ear.”
