Dear Seq Fans, If you look on YouTube for a musical work by the famous
Danish composer Per Nørgård called "Iris" or maybe "voyage into the golden
screen", you see something that looks like a sequence written around a
spiral.

One of these links may work, depending on what country you are in:

Per Nørgård [Noergaard], <a href="
https://www.youtube.com/watch?v=wc8GvMkjGBc">Voyage into the golden
screen</a>, on YouTube.

https://www.youtube.com/watch?v=ELIA88kHJr4

Could someone convert this to a sequence for the OEIS?

(The infinity sequence is another work of his, for which the sequence is
A004718)

The test for success would be that when you click the listen button on the
OEIS entry,  you hear something that is an approximation to the musical
work.
